Description

Rabbit Polyclonal Antibody

Specifically detects PTRF/Cavin-1 Clone: in Human, Rat samples, and it is validated for Immunocytochemistry, Immunohistochemistry (Paraffin), Western Blotting

Polymerase I and transcript release factor (UniProt Q6NZI2; also known as Cavin-1, PTRF, RNA polymerase I and transcript release factor, TTF-I interacting peptide 12) is encoded by the PTRF (also known as CGL4, CAVIN, CAVIN1, FKSG13) gene (Gene ID 284119) in human. Cavin-1 is the founding member of the PTRF/Cavin family of cytoplasmic proteins whose expressions are essential for caveola formation. PTRF/Cavin-1, serum deprivation response (SDR)/Cavin-2, SDR-related gene product that binds to C kinase (SRBC)/Cavin-3, and muscle-restricted coiled-coil protein (MURC)/Cavin-4, form an oligomeric assembly termed Cavin complex in the cytosol and associate with caveolin at plasma membrane caveolae. Research shows an essential role for PTRF/Cavin-1 but not the other family members in caveola formation and recruitment of the cavin complex to the plasma membrane. In prostate cancer PC3 cells and during development of zebrafish notochord, lack of PTRF-Cavin expression correlates with lack of caveolae, where caveolin displays increased lateral mobility on the plasma membrane and accelerated lysosomal degradation. Expression of Cavin-1 restores caveolae formation in PC3 cells. Likewise the absence of cavin-1 is also observed in advanced prostate carcinoma. PTRF gene mutations are known to cause congenital generalized lipodystrophy 4 (CGL4).
