CDK11B

Functionⁱ

Plays multiple roles in cell cycle progression, cytokinesis and apoptosis. Involved in pre-mRNA splicing in a kinase activity-dependent manner. Isoform 7 may act as a negative regulator of normal cell cycle progression.4 Publications

Miscellaneous

Duplicated gene. CDK11A and CDK11B encode almost identical protein kinases of 110 kDa that contain at their C-termini the open reading frame of a smaller 58 kDa isoform which is expressed following IRES-mediated alternative initiation of translation.

Caution

Many references talk about 'p110 isoforms' but it is not yet known if this refers to CDK11A and/or CDK11B or one/some of the isoforms of each.Curated

Interactionⁱ

Subunit structureⁱ

Cleaved isoform SV9 (p110C) binds to the serine/threonine kinase PAK1 and RANBP9. p110C interacts with RNPS1. Isoform 7, but not isoform SV9, nor its cleavage product p110C, interacts with CCND3. Interacts with CCNL1 and CCNL2. Forms complexes with pre-mRNA-splicing factors, including at least SRSF1, SRSF2 AND SRSF7/SLU7. Interacts with isoform 5 of MYO18A (PubMed:25965346).5 Publications
