YDR061W is an antibody targeting the YDR061W gene product in Saccharomyces cerevisiae (Baker’s yeast). This antibody is primarily used in research to study the protein’s structure, function, and role in yeast biology. The YDR061W gene encodes a protein associated with ABC (ATP-binding cassette) transporters, a critical family of membrane proteins involved in substrate transport across cellular membranes . While the precise biological role of YDR061W remains partially uncharacterized, it has been implicated in multidrug resistance and cellular detoxification pathways .
YDR061W antibody (Product Code: CSB-PA623603XA01SVG) is commercially available for applications such as:
Western Blotting: Detects YDR061W protein expression in yeast lysates .
Immunofluorescence: Localizes the protein within cellular compartments .
Functional Studies: Investigates roles in drug resistance and substrate transport .
YDR061W is part of the pleiotropic drug resistance (PDR) network in yeast, alongside transporters like Pdr5p and Snq2p . Studies using knockout strains suggest its involvement in efflux of xenobiotics, although its substrate specificity is less defined compared to Yor1p or Ycf1p .
In Vitro Transport: While YDR061W itself has not been directly assayed, related ABC transporters (e.g., Ycf1p) utilize ATP/GTP hydrolysis to power substrate translocation .
Mutational Analysis: Studies on homologous proteins highlight critical residues in ATP-binding domains that could inform YDR061W’s mechanism .
Deletion of YDR061W in yeast does not result in overt growth defects under standard conditions but may sensitize cells to specific toxins, as observed in strains lacking ABC transporters .

YDR061W is a protein found in Saccharomyces cerevisiae (baker's yeast), specifically in the reference strain ATCC 204508/S288c. This protein has been identified as one of the ABC (ATP-binding cassette) proteins in yeast, though notably, it is not closely homologous to any mammalian proteins in this family . The protein is encoded by the YDR061W gene and has the UniProt accession number Q12298 .
From a biological perspective, YDR061W belongs to a class of proteins that typically function as transporters, though its specific substrate specificity and biological role remain less characterized compared to other yeast ABC transporters such as Ycf1p. The study of YDR061W can provide insights into the evolution and diversification of ABC transporters in fungi compared to other eukaryotes, particularly since it lacks close mammalian homologs.

This antibody has been validated for ELISA and Western Blot applications, making it suitable for detecting and studying YDR061W protein expression in yeast samples .
While the search results don't provide explicit structural comparison data for YDR061W versus other ABC transporters, we can infer its relationship from contextual information. In the ABC transporter family, YDR061W is mentioned as distinct from the well-characterized transporters like Ycf1p .
Most yeast ABC transporters share a common architecture with:
Nucleotide-binding domains (NBDs) that bind and hydrolyze ATP
Membrane-spanning domains (MSDs) that form the translocation pathway
In some cases, additional domains like N-terminal extensions (NTEs)
Unlike Ycf1p and other MRP family transporters that have been extensively studied for their roles in detoxification and metabolite transport, YDR061W's precise transport capabilities and substrates remain less defined. This suggests opportunities for researchers to characterize this protein's role in yeast cellular processes through targeted experiments utilizing the YDR061W antibody.
When designing Western blot protocols for YDR061W detection, researchers should consider the following methodology:

When planning dual-labeling experiments that include YDR061W antibody, researchers must consider several factors to ensure successful multiplexing:
Host Species Considerations:
For dual labeling, select secondary antibodies with:
Different host species (e.g., mouse, goat)
Non-cross-reactive secondaries
Fluorophore Selection for Immunofluorescence:
Choose fluorophores with minimal spectral overlap
Recommended combinations:
YDR061W (rabbit) + Alexa Fluor 488
Second target (mouse) + Alexa Fluor 594/647
Sequential vs. Simultaneous Staining:
For membrane proteins, sequential staining often yields better results
For different cellular compartments, simultaneous staining may work well
Western Blot Considerations:
If targets have similar molecular weights:
Strip and reprobe membrane sequentially
Use differently colored detection systems (e.g., red and green fluorescent secondaries)
If targets have different molecular weights:
Cut membrane horizontally and probe sections separately
Control Experiments for Dual Labeling:
Single primary antibody controls with both secondary antibodies
Secondary-only controls
Absorption controls with specific blocking peptides
| Secondary Combination | Target 1: YDR061W | Target 2 | Notes |
|---|---|---|---|
| Fluorescent | Anti-rabbit Alexa 488 | Anti-mouse Alexa 594 | Good spectral separation |
| Enzymatic | Anti-rabbit HRP | Anti-mouse AP | Use different substrates (e.g., TMB and NBT/BCIP) |
| Mixed detection | Anti-rabbit HRP | Anti-mouse fluorescent | Combine chemiluminescent and fluorescent imaging |
| Magnetic beads | Anti-rabbit magnetic beads | Anti-mouse magnetic beads (different color) | For cell sorting or co-IP experiments |
Following these considerations will help ensure clean, specific labeling when using YDR061W antibody in multiplexed experiments.

Relevance to ABC Transporter Biology:
The yeast genome encodes multiple ABC transporters with diverse functions. While specific YDR061W interactions aren't detailed in the search results, similar proteins like Ycf1p have been shown to interact with other cellular components . As noted in research on Ycf1p, "NBD1 may functionally interact with NBD2, MSD1, and MSD2 for proper Ycf1p function" , suggesting that such domain interactions could be studied in YDR061W as well.
Investigating these interactions could help determine whether YDR061W participates in larger complexes or networks involving other transporters, potentially providing insights into functional redundancy or specialization among yeast ABC transporters.

Titrate antibody concentrations for each method
Document assay-specific optimal conditions
Perform complementary experiments:
If Western blot shows a band but immunofluorescence is negative:
Check subcellular fractionation to confirm protein location
Verify fixation methods aren't destroying epitopes
If ELISA is positive but Western blot is negative:
Test different protein extraction methods
Consider native vs. denaturing conditions
Evaluate biological context:
Protein expression levels may vary with growth conditions
