YLR042C Antibody

Gene Overview: YLR042C (NFG1)

YLR042C is a yeast gene located on chromosome XII. Key features include:

Biological Role of NFG1

NFG1 interacts with pathways controlling filamentous growth and cell wall integrity:

• Invasive Growth Suppression: NFG1 negatively regulates the mitogen-activated protein kinase (MAPK) pathway, which drives pseudohyphal growth. Deletion of NFG1 enhances invasive growth in yeast .

• Cell Wall Stress Response: NFG1 is implicated in the Cell Wall Integrity (CWI) pathway, with transcriptional upregulation under stress (e.g., Calcofluor white exposure) .

• Genetic Interactions: NFG1 works alongside RPI1, RGD2, and TIP1 to limit hyperactivation of invasive growth pathways .

YLR042C Antibody: Applications and Research Findings

While no commercial YLR042C antibody is explicitly described in the provided sources, antibodies targeting yeast proteins in similar studies provide context for its hypothetical use:

Key Research Context

• Colony Immunoblots: Anti-HA antibodies (as in ) are used to detect epitope-tagged proteins like NFG1 in yeast colonies. Such methods quantify protein shedding (e.g., Flo11p) under inducing conditions .

• MAPK Pathway Analysis: Antibodies against phosphorylated MAP kinases (e.g., anti-phospho-p44/p42) are employed to study pathway activation states . A YLR042C antibody could similarly monitor NFG1 expression or post-translational modifications.

• Flow Cytometry: Antibody-conjugated fluorescent probes (e.g., GFP fusions) enable tracking of NFG1 dynamics during stress responses .
