| Product Name | CHMP4A, 1-265aa, Human |
|---|---|
| Description | CHMP4A (Chromatin-modifying protein 4a) belongs to the SNF7 family and functions as chromatin-modifying proteins. It probable core 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. Also during HIV-1 infection, the virus uses the ESCRT-III complex to mediate budding and exocytosis of viral proteins via the association of CHMP4 and a protein recruited by HIV-1 p6, which is present in viral Gag assembly and budding. CHMP4A expressed at higher level in heart, kidney, liver and skeletal muscle. Recombinant human CHMP4A protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques. |
