About This Section

Entrez Gene summary for CIT Gene:

This gene encodes a serine/threonine-protein kinase that functions in cell division. Together with the kinesin

KIF14, this protein localizes to the central spindle and midbody, and functions to promote efficient cytokinesis.

This protein is involved in central nervous system development. Polymorphisms in this gene are associated with

bipolar disorder and risk for schizophrenia. Alternative splicing results in multiple transcript variants.

(provided by RefSeq, Aug 2011)

GeneCards Summary for CIT Gene:

CIT (citron (rho-interacting, serine/threonine kinase 21)) is a protein-coding gene. Diseases associated with CIT include bipolar disorder, and down syndrome critical region, and among its related super-pathways are ERK Signaling and Cellular Effects of Sildenafil. GO annotations related to this gene include SH3 domain binding and protein serine/threonine kinase activity. An important paralog of this gene is CDC42BPG.

UniProtKB/Swiss-Prot: CTRO_HUMAN, O14578

Function: Plays a role in cytokinesis. Required for KIF14 localization to the central spindle and midbody.

Putative RHO/RAC effector that binds to the GTP-bound forms of RHO and RAC1. It probably binds p21 with a tighter

specificity in vivo. Dual specificity protein kinase activity catalyzing autophosphorylation and phosphorylation

of exogenous substrates on both serine/threonine and tyrosine residues. Plays an important role in the regulation

of cytokinesis and the development of the central nervous system. Phosphorylates MYL9/MLC2
