Crystal structure of the third RCC1-like domain of HERC1Crystal structure of the third RCC1-like domain of HERC1

Structural highlights

4o2w is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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]
