Supplementary information

The protein charged multivesicular body protein 1a (CHMP1a) is an essential component of the endosomal sorting complex required for transport (ESCRT)-III also known as chromatin-modifying protein 1A. CHMP1a has a molecular mass of approximately 22 kDa. It shows expression in various tissues with significant presence observed in the brain liver and kidneys. CHMP1a plays a role in the cellular process of membrane remodeling and vesicle trafficking.
Biological function summary

CHMP1a assists in cellular processes like cytokinesis and maintenance of chromatin structure. It is an important part of the ESCRT-III complex which is important for the final stages of cell division and intracellular sorting processes. CHMP1a contributes to the degradation of membrane proteins in lysosomes and the maintenance of proper cell function by controlling the fate of cell surface receptors.

Pathways

The ESCRT-III complex including CHMP1a is involved in the endosomal-lysosomal degradation pathway. This pathway plays a critical role in the down-regulation of cell signaling. CHMP1a associates with proteins such as VPS4 which is involved in the disassembly and recycling of the ESCRT-III complex for repeated use in successive cell cycles. CHMP1a also contributes to the proper functioning of the mitotic spindle assembly ensuring successful mitosis.

Defects or mutations in CHMP1a expression can associate with neurodegenerative diseases like frontotemporal dementia. Research shows implications in cancer with altered CHMP1a expression affecting tumor progression due to disrupted cell division and regulation. The proteins within its pathways such as TSG101 and ALIX also exhibit connections to oncogenic processes further highlighting the role of CHMP1a in pathological conditions.

General info

Function

Probable peripherally associated component of the endosomal sorting required for transport complex III (ESCRT-III) which is involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. The MVB pathway appears to require the sequential function of ESCRT-O, -I,-II and -III complexes. ESCRT-III proteins mostly dissociate from the invaginating membrane before the ILV is released. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and the budding of enveloped viruses (HIV-1 and other lentiviruses). ESCRT-III proteins are believed to mediate the necessary vesicle extrusion and/or membrane fission activities, possibly in conjunction with the AAA ATPase VPS4. Involved in cytokinesis. Involved in recruiting VPS4A and/or VPS4B to the midbody of dividing cells. May also be involved in chromosome condensation. Targets the Polycomb group (PcG) protein BMI1/PCGF4 to regions of condensed chromatin. May play a role in stable cell cycle progression and in PcG gene silencing.
