The protein contains 404 amino acids for an estimated molecular weight of 45518 Da.
Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase. (updated: April 1, 2015)

See 188830. Phosphorylation by cAMP-dependent protein kinases is essential for sperm motility. A cAMP-dependent protein kinase is bound to sperm flagella by a regulatory subunit (RII). Oyen et al. (1989) observed high testis-specific expression of a human homolog to the rat RII-alpha mRNA induced in haploid germ cells. They cloned a human cDNA that encodes a 404-amino acid polypeptide with a region (amino acids 45-75) divergent from that of the previously published mouse and rat sequences. By PCR and Southern blot analysis of somatic cell hybrid mapping panels and by radiation hybrid analysis, Tasken et al. (1998) mapped the PRKAR2A gene to chromosome 3p21.3-p21.2. ...
