Description
Charged multivesicular body protein 1a, also known as CHMP1A, belongs to the vacuolar sorting protein family and functions as chromatin-modifying protein. These complexes are crucial for sorting endosomal articles into multivesicular bodies (MVBs), as well as required for the formation of these bodies. The MVBs pathway mediates delivery of transmembrane proteins into the lumen of the lysosome for degradation. CHMP1 interacts with VPS4B and localizes to early endosomes. Two isoforms, encoded by distinct genes, exists for CHMP1. They are designated CHMP1A and CHMP1B
