Summaries for PKIB Gene

Entrez Gene Summary for PKIB Gene

  • This gene encodes a member of the cAMP-dependent protein kinase inhibitor family. The encoded protein may play a role in the protein kinase A (PKA) pathway by interacting with the catalytic subunit of PKA, and overexpression of this gene may play a role in prostate cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

GeneCards Summary for PKIB Gene

PKIB (CAMP-Dependent Protein Kinase Inhibitor Beta) is a Protein Coding gene. Among its related pathways are Signal transduction_PKA signaling and Activation of cAMP-Dependent PKA. Gene Ontology (GO) annotations related to this gene include cAMP-dependent protein kinase inhibitor activity.

UniProtKB/Swiss-Prot for PKIB Gene

  • Extremely potent competitive inhibitor of cAMP-dependent protein kinase activity, this protein interacts with the catalytic subunit of the enzyme after the cAMP-induced dissociation of its regulatory chains.
