About CHMP4A

Cytogenetic location: 14q12 Genomic coordinates (GRCh38): 14:24,209,615-24,213,488 (from NCBI)

This gene has 10 transcripts (splice variants), 1 gene allele, 77 orthologues and 4 paralogues. Ubiquitous expression in fat (RPKM 27.3), lymph node (RPKM 25.9) and 25 other tissues.

Summary

CHMP4A belongs to the chromatin-modifying protein/charged multivesicular body protein (CHMP) family. These proteins are components of ESCRT-III (endosomal sorting complex required for transport III), a complex involved in degradation of surface Receptor Proteins and formation of endocytic multivesicular bodies (MVBs). Some CHMPs have both nuclear and cytoplasmic/vesicular distributions, and one such CHMP, CHMP1A (MIM 164010), is required for both MVB formation and regulation of cell cycle progression (Tsang et al., 2006 [PubMed 16730941]).[supplied by OMIM, Mar 2008]
