PROTEIN SUMMARY GENE INFORMATION RNA DATA ANTIBODY DATA
GENERAL INFORMATIONi

General description of the gene and the encoded protein(s) using information from HGNC and Ensembl, as well as predictions made by the Human Protein Atlas project.

Gene namei

Official gene symbol, which is typically a short form of the gene name, according to HGNC.

CIT
Synonyms CITK, CRIK, KIAA0949, STK21
Gene descriptioni

Full gene name according to HGNC.

Citron rho-interacting serine/threonine kinase
Protein classi

Assigned HPA protein class(es) for the encoded protein(s).

Disease related genes
Enzymes
Human disease related genes
Potential drug targets
Predicted locationi

All transcripts of all genes have been analyzed regarding the location(s) of corresponding protein based on prediction methods for signal peptides and transmembrane regions.

  • Genes with at least one transcript predicted to encode a secreted protein, according to prediction methods or to UniProt location data, have been further annotated and classified with the aim to determine if the corresponding protein(s) are secreted or actually retained in intracellular locations or membrane-attached.

  • Remaining genes, with no transcript predicted to encode a secreted protein, will be assigned the prediction-based location(s).

The annotated location overrules the predicted location, so that a gene encoding a predicted secreted protein that has been annotated as intracellular will have intracellular as the final location.

PROTEIN FUNCTION
Protein function (UniProt)i

Useful information about the protein provided by UniProt.

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. Displays serine/threonine protein kinase activity. Plays an important role in the regulation of cytokinesis and the development of the central nervous system. Phosphorylates MYL9/MLC2.... show less
Molecular function (UniProt)i

Keywords assigned by UniProt to proteins due to their particular molecular function.

Developmental protein, Kinase, Serine/threonine-protein kinase, Transferase
Biological process (UniProt)i

Keywords assigned by UniProt to proteins because they are involved in a particular biological process.

Cell cycle, Cell division, Differentiation, Mitosis, Neurogenesis
Ligand (UniProt)i

Keywords assigned by UniProt to proteins because they bind, are associated with, or whose activity is dependent of some molecule.

ATP-binding, Metal-binding, Nucleotide-binding, Zinc
Gene summary (Entrez)i

Useful information about the gene from Entrez

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]... show less
PROTEIN INFORMATIONi

The protein information section displays alternative protein-coding transcripts (splice variants) encoded by this gene according to the Ensembl database.

The Splice variant identifier links to the Ensembl website protein summary for the selected splice variant. The data in the Swissprot and TrEMBL columns links to corresponding pages in the UniProt database.

The protein classes assigned to this protein are shown if expanding the data in the protein class column. Parent protein classes are in bold font and subclasses are listed under the parent class.

The length of the protein (amino acid residues according to Ensembl), molecular mass (kDalton), predicted signal peptide and number of predicted transmembrane region(s) according to in-house majority decision methods based on sets of predictors are also reported.
