Anti-phospho Charged Multivesicular Body Protein 4c, Ser210/214/215 [pCHMP4C] Antibody

This rabbit IgG1 polyclonal antiobody was generated against a synthetic peptide (TARRSRAASSQRAEEC) and recognizes mammalian forms of Phospho Charged multi vesicular protein 4c.

Borealin interacts directly with Snf7/Shrb/CHMP4 components in both Drosophila and human cells and the two proteins colocalize at the midbody in late cytokinesis. Aurora B phosphorylates CHMP4C at three serine residues located in its C-terminal linker region, a part of the protein known to regulate its ability to form polymers and interact with the membrane. Over-expression of CHMP4C variants mutated in these three residues caused cytokinesis failure, suggesting that Aurora B inhibits CHMP4C activity during cytokinesis. It is proposed that CPC controls abscission timing in both flies and human cells by regulating the function of ESCRT-III Snf7 proteins during cytokinesis through the interaction of its Borealin component with the N-terminus of Shrb/CHMP4 proteins and Aurora B-mediated phosphorylation of the CHMP4C regulatory linker tail.
