The FAM212ab antibody is a zebrafish-specific monoclonal antibody designed to target the FAM212ab protein, a member of the family with sequence similarity 212 (FAM212) family. This antibody is primarily utilized in diagnostics and therapeutic antibody development, leveraging its specificity to synthetic peptides in the N-, C-, and M-terminal regions of the FAM212ab protein . Its applications span immunological research, disease modeling, and drug discovery.
The FAM212ab protein (gene symbol: fam212ab) is annotated as Zgc:66438 in zebrafish, with a predicted length of 288 amino acids . While its precise biological function remains understudied, paralogs like FAM212B in mammals (e.g., humans) are known to inhibit serine/threonine kinases such as PAK4, suggesting potential roles in cytoskeletal regulation or signaling pathways .
The FAM212ab antibody is validated for:
Western Blot (WB): Detects 1 ng of target protein in zebrafish lysates .
Immunohistochemistry (IHC): Enables tissue localization studies in zebrafish models .
Its design as a combination of monoclonal antibodies (mAbs) against multiple epitopes enhances specificity and reduces cross-reactivity . This approach is critical for targeting proteins with conserved motifs across species or paralogs.
FAM21: Studies in mammalian systems reveal its role in endosome dynamics and immune signaling . FAM21-knockout dendritic cells show impaired antigen presentation, highlighting FAM proteins’ broader immunological relevance .
FAM212B: A human paralog inhibits PAK4 kinase, linking FAM proteins to cytoskeletal regulation and oncogenic pathways .
FAM212ab antibodies are pivotal in zebrafish studies of development and disease. For example, FAM proteins’ roles in innate immunity and vesicle trafficking suggest translational potential for human diseases like fibrosis or cancer .
