Calcium-binding protein 39 is a protein

Protein

Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

 that in humans is encoded by the CAB39 gene

Gene

A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

LYK5

Protein kinase LYK5, also known as LYK5 or STRADα, is a human protein and also denotes the gene encoding it.-Function:Endogenous LKB1 and STRADα form a complex in which STRADα activates LKB1, resulting in phosphorylation of both partners...

(STE20-Related ADaptor protein). CAB39 enhances formation of STK11/STRAD complexes and stimulates STK11 catalytic activity. CAB39 may function as a scaffolding component of the STK11/STRAD complex and regulates STK11 activity and cellular localization.
