Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. When bound to KRT17, regulates protein synthesis and epithelial cell growth by stimulating Akt/mTOR pathway. Homodimer. Interacts with KRT17 and SAMSN1. Found in a complex with XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29, VPS35 and SFN. Interacts with GAB2. Interacts with SRPK2. Present mainly in tissues enriched in stratified squamous keratinizing epithelium. Belongs to the 14-3-3 family. 2 isoforms of the human protein are produced by alternative splicing.

Molecular Function: protein binding; protein kinase C inhibitor activity
Biological Process: DNA damage response, signal transduction by p53 class mediator resulting in cell cycle arrest; DNA damage response, signal transduction resulting in induction of apoptosis; negative regulation of caspase activity; negative regulation of protein kinase activity; positive regulation of epidermal cell differentiation; regulation of epidermal cell division; release of cytochrome c from mitochondria; signal transduction
