CC -!- FUNCTION: Adapter protein implicated in the regulation of a large
CC spectrum of both general and specialized signaling pathways. Binds to a
CC large number of partners, usually by recognition of a phosphoserine or
CC phosphothreonine motif. Binding generally results in the modulation of
CC the activity of the binding partner. When bound to KRT17, regulates
CC protein synthesis and epithelial cell growth by stimulating Akt/mTOR
CC pathway. May also regulate MDM2 autoubiquitination and degradation and
CC thereby activate p53/TP53 (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Found in a complex with XPO7, EIF4A1, ARHGAP1,
CC VPS26A, VPS29 and VPS35. Interacts with KRT17. Interacts with GAB2 and
CC SAMSN1 (By similarity). Interacts with SRPK2 (By similarity). Interacts
CC with COPS6 (By similarity). Interacts with COP1; this interaction leads
CC to proteasomal degradation (By similarity). Interacts with the 'Thr-
CC 369' phosphorylated form of DAPK2 (By similarity). Interacts with PI4KB
CC (By similarity). Interacts with SLITRK1 (By similarity). Interacts with
CC LRRK2; this interaction is dependent on LRRK2 phosphorylation (By
CC similarity). {ECO:0000250, ECO:0000250|UniProtKB:O70456,
CC ECO:0000250|UniProtKB:P31947}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC Secreted {ECO:0000250}. Note=May be secreted by a non-classical
CC secretory pathway. {ECO:0000250}.
CC -!- PTM: Ubiquitinated. Ubiquitination by RFFL induces proteasomal
CC degradation and indirectly regulates p53/TP53 activation (By
CC similarity). {ECO:0000250}.
CC -!- MISCELLANEOUS: 14-3-3 proteins have been shown to be PKC activators,
CC but this effect could be non-specific and only due to the acidic nature
CC of the protein.
CC -!- SIMILARITY: Belongs to the 14-3-3 family. {ECO:0000305}.
