Present mainly in tissues enriched in stratified squamous keratinizing epithelium.

Description:
14-3-3 proteins regulate many cellular processes relevant to cancer biology, notably apoptosis, mitogenic signaling and cell-cycle checkpoints. Seven isoforms, denoted 14-3-3 b, g, e, z, h, q and s, comprise this family of signaling intermediates. 14-3-3 s, also known as SFN, stratifin, HME1 or YWHAS, is a secreted adaptor protein that is involved in regulating both general and specific signaling pathways. Expressed predominately in stratified squamous keratinising epithelium, 14-3-3 s is able to bind and modify the activity of a large number of proteins, such as KRT17 (Keratin 17), through recognition of a phosphothreonine or phosphoserine motif. When bound to Keratin 17, for example, 14-3-3 s acts to stimulate the Akt/mTOR signaling pathway by upregulating protein synthesis and cell growth. 14-3-3 s also functions to positively mediate IGF-I-induced cell cycle progression and can bind to a variety of translation initiation factors, thus controlling mitotic translation. In response to tumor growth, 14-3-3 s positively regulates the tumor suppressor p53 and increases the rate of p53-regulated inhibition of G2/M cell cycle progression. Multiple isoforms of 14-3-3 s exist due to alternative splicing events.

Research Backgrounds

Function:

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. May also regulate MDM2 autoubiquitination and degradation and thereby activate p53/TP53.

p53-regulated inhibitor of G2/M progression.

PTMs:

Ubiquitinated. Ubiquitination by RFFL induces proteasomal degradation and indirectly regulates p53/TP53 activation.

Subcellular Location:

Cytoplasm. Nucleus. Secreted.
Note: May be secreted by a non-classical secretory pathway.

Tissue Specificity:

Present mainly in tissues enriched in stratified squamous keratinizing epithelium.

Subunit Structure:

Homodimer. Interacts with KRT17 and SAMSN1 (By similarity). Found in a complex with XPO7, EIF4A1, ARHGAP1, VPS26A, VPS29 and VPS35. Interacts with GAB2. Interacts with SRPK2. Interacts with COPS6. Interacts with COP1; this interaction leads to proteasomal degradation. Interacts with the 'Thr-369' phosphorylated form of DAPK2. Interacts with PI4KB. Interacts with SLITRK1.
