Secondary Information

Presence in other biological fluids/tissue/cells abundant in the brain, comprising approximately 1% of its total soluble protein ; also present in almost all tissues, including testes, liver, and heart
Protein Function are highly conserved dimeric proteins; involvement in vital cellular processes, such as metabolism, protein trafficking, signal transduction, apoptosis and cell-cycle regulation; 14–3–3sigma is a putative tumor suppressor that is transactivated by p53 in response to DNA damage; when up-regulated, 14–3–3s induces S–G1 and G2–M cell cycle arrests; 14-3-3γ is critical for maintaining cellular homeostasis and signal transduction; 14-3-3γ is also an important factor for intracellular phosphorylation, which participates in various pathophysiological processes; 14-3-3 maintains Raf-1 in an inactive state in the absence of activation signals but promotes Raf-1 activation and stabilizes its active conformation when such signals are received; 14-3-3 isoforms may ensure DNA damage-induced cell cycle arrest.  14-3-3 β/α-A protein as a novel maternal peptidoglycan-binding protein that protects embryos of zebrafish against bacterial infections
Biochemical Properties acidic isoelectric point of 4–5; primarily binds phosphorylated ligands; also capable of interacting with unphosphorylated ligands; activation of the ExoS ADP-ribosyltransferase (12, 13) and of tryptophan hydroxylase; activator of the 43-kDa inositol polyphosphate 5-phosphatase
Significance in milk 14-3-3 sigma regulates epithelial polarity in mammary gland as found in humans; 14-3-3γ Regulates Lipopolysaccharide-Induced Inflammatory Responses and Lactation in Dairy Cow Mammary Epithelial Cells
PTMs Phosphorylation of 14-3-3 appears to modulate the function of 14-3-3 isoforms. Three phosphorylation sites have been determined in 14-3-3eta: S58, S184, and T232; in mammalian isoforms, only 14-3-3sigma and 14-3-3eta have a phosphorylation site at the corresponding 232 position
Significance of PTMs regulate ligand binding activity; phosphorylated forms of beta and eta show increased potency in the inhibition of PKC in vitro
Additional Comments  14-3-3 Protein beta/alpha may be a diagnostically useful biomarker for early diagnosis of renal cell carcinoma (RCC).
