Crystal structure of the third RCC1-like domain of HERC1
Function
[HERC1_HUMAN] Involved in membrane trafficking via some guanine nucleotide exchange factor (GEF) activity and its ability to bind clathrin. Acts as a GEF for Arf and Rab, by exchanging bound GDP for free GTP. Binds phosphatidylinositol 4,5-bisphosphate, which is required for GEF activity. May also act as a E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates.[1] [2] [3]
About this Structure
4o2w is a 4 chain structure. Full crystallographic information is available from OCA.
