DESCRIPTION

Also known as PRC1_HUMAN, PRC1. Key regulator of cytokinesis that cross-links antiparrallel microtubules at an average distance of 35 nM. Essential for controlling the spatiotemporal formation of the midzone and successful cytokinesis. Required for KIF14 localization to the central spindle and midbody. Required to recruit PLK1 to the spindle. Stimulates PLK1 phosphorylation of RACGAP1 to allow recruitment of ECT2 to the central spindle. Acts as an oncogene for promoting bladder cancer cells proliferation, apoptosis inhibition and carcinogenic progression (PubMed:17409436). Homodimer (PubMed:20691902). Interacts with the C-terminal Rho-GAP domain and the basic region of RACGAP1 (PubMed:14744859). The interaction with RACGAP1 inhibits its GAP activity towards CDC42 in vitro, which may be required for maintaining normal spindle morphology (PubMed:14744859). Interacts (via N-terminus) with the C-terminus of CENPE (via C-terminus); the interaction occurs during late mitosis (PubMed:15297875). Interacts (via N-terminus) with KIF4A (via C-terminus); the interaction is required for the progression of mitosis (PubMed:15297875, PubMed:16431929, PubMed:29848660). Interacts (via N-terminus) with KIF23 (via C-terminus); the interaction occurs during late mitosis (PubMed:15297875). Interacts with KIF14 and KIF20A (PubMed:15625105, PubMed:16431929). Interacts with PLK1 (PubMed:19468300). Interacts with KIF20B (PubMed:17409436).
