Entrez Gene Summary for CKS1B Gene

  • CKS1B protein binds to the catalytic subunit of the cyclin dependent kinases and is essential for their biological function. The CKS1B mRNA is found to be expressed in different patterns through the cell cycle in HeLa cells, which reflects a specialized role for the encoded protein. At least two transcript variants have been identified for this gene, and it appears that only one of them encodes a protein. [provided by RefSeq, Sep 2008]

GeneCards Summary for CKS1B Gene

CKS1B (CDC28 Protein Kinase Regulatory Subunit 1B) is a Protein Coding gene. Diseases associated with CKS1B include mantle cell lymphoma.
