Results show that endogenous levels of Pkig reciprocally regulate osteoblast and adipocyte differentiation and that this reciprocal regulation is mediated in part by LIF.
These results indicate that the downregulation of PKIgamma may be prerequisite for the PKA activation during the osteoblastic differentiation of precursor cells.

endogenous levels of PKI regulate PKA signaling
The protein encoded by this gene is a member of the cAMP-dependent protein kinase (PKA) inhibitor family. Studies of a similar protein in mice suggest that this protein acts as a potent competitive PKA inhibitor, and is a predominant form of PKA inhibitors in various tissues. Three alternatively spliced transcript variants encoding the same protein have been reported.
