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. Homodimer. Interacts with SAMSN1. Interacts with RAF1, SSH1 and CRTC2/TORC2. Interacts with ABL1 (phosphorylated form); the interaction retains it in the cytoplasm. Interacts with GAB2. Interacts with MDM4 (phosphorylated); negatively regulates MDM4 activity toward TP53. Interacts with PKA-phosphorylated AANAT. Highly expressed in brain, skeletal muscle, and heart. Belongs to the 14-3-3 family. Note: This description may include information from UniProtKB.
