Protein
Centrosomal protein of 55 kDa
Gene
Cep55
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Plays a role in mitotic exit and cytokinesis. Not required for microtubule nucleation. Recruits PDCD6IP and TSG101 to midbody during cytokinesis By similarity.

Note: Present at the centrosomes at interphase. A small portion is associated preferentially with the mother centriole, whereas the majority localizes to the pericentriolar material. During mitosis, loss of affinity for the centrosome at the onset of prophase and diffusion throughout the cell. Dissociation from the centrosome is phosphorylation-dependent. May remain localized at the centrosome during mitosis in certain cell types. Appears at the cleavage furrow in late anaphase and in the midbody in cytokinesis By similarity.

Post-translational modificationi

There is a hierachy of phosphorylation, where both Ser-423 and Ser-426 are phosphorylated at the onset of mitosis, prior to Ser-434. Phosphorylation at Ser-423 and Ser-426 is required for dissociation from the centrosome at the G2/M boundary. Phosphorylation at the 3 sites, Ser-423, Ser-426 and Ser-434, is required for protein function at the final stages of cell division to complete cytokinesis successfully By similarity.

Interactioni

Subunit structurei

Homodimer. Interacts (phosphorylated on Ser-423 and Ser-426) with PLK1. Interacts with AKAP9; the interaction occurs in interphase and is lost upon mitotic entry. Interacts with PCNT; the interaction occurs in interphase and is lost upon mitotic entry. Interacts with PDCD6IP; the interaction is direct; CEP55 binds PDCD6IP in a 2:1 stoechiometry; PDCD6IP competes with TSG101 for the same binding site. Interacts with TSG101; TSG101 competes with PDCD6IP for the same binding site; interaction is required for cytokinesis. Interacts with MVB12A, VPS37B, VPS37C and VPS28 By similarity.
