Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Specificity / Sensitivity
FAM129B Antibody recognizes endogenous levels of total FAM129B protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu705 of human Fam129B protein. Antibodies were purified by protein A and peptide affinity chromatography.

FAM129B/Niban-like protein 1 (family with sequence similarity 129, member B) belongs to a poorly characterized family of Niban proteins that also includes FAM129A/Niban and FAM129C/Niban-like protein 2. FAM129A/Niban is implicated in the ER stress response and is upregulated at the protein level in thyroid carcinoma (1,2). FAM129C/Niban-like protein 2 is preferentially expressed in B-cells and is one of five biomarkers upregulated in whole blood from patients with colorectal carcinoma (3,4). FAM129B is broadly expressed and has been shown to be a downstream target of B-Raf in melanoma cells (5). Though FAM129B does not appear to regulate cell growth and division, phosphorylation of FAM129B by B-Raf is essential for the invasive potential of melanoma and non-melanoma cell lines (5). Deletion of FAM129B in melanoma cells significantly impairs B-Raf/MEK/Erk-dependent invasion into the extracellular matrix (5).
