Centrosomal protein of 152 kDa - O94986 (CE152_HUMAN)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Necessary for centrosome duplication; the function seems also to involve CEP63, CDK5RAP2 and WDR62 through a stepwise assembled complex at the centrosome that recruits CDK2 required for centriole duplication (PubMed:26297806). Acts as a molecular scaffold facilitating the interaction of PLK4 and CENPJ, 2 molecules involved in centriole formation (PubMed:21059844, PubMed:20852615). Proposed to snatch PLK4 away from PLK4:CEP92 complexes in early G1 daughter centriole and to reposition PLK4 at the outer boundary of a newly forming CEP152 ring structure (PubMed:24997597). Also plays a key role in deuterosome-mediated centriole amplification in multiciliated that can generate more than 100 centrioles (By similarity). Overexpression of CEP152 can drive amplification of centrioles (PubMed:20852615). UniProt

Subunit Structure
Interacts (via N-terminus) with PLK4; the interaction is mutally exclusive with a PLK4:CEP192 interaction (PubMed:21059844, PubMed:20852615, PubMed:24997597). Interacts (via C-terminus) with CENPJ (via-N-terminus) (PubMed:20852615). Interacts with CINP (PubMed:21131973). Interacts with CDK5RAP2, WDR62, CEP63 and CEP131 (PubMed:21983783, PubMed:24613305, PubMed:26297806). CEP63, CDK5RAP2, CEP152, WDR62 are proposed to form a stepwise assembled complex at the centrosome forming a ring near parental centrioles (PubMed:26297806). Interacts with DEUP1; this interaction recruits CEP152 to the deuterosome. The interactions with CEP63 and DEUP1 are mutually exclusive (By similarity). UniProt

Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
