YWHAZ

This gene product belongs to the 14-3-3 family of proteins which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals, and this protein is 99% identical to the mouse, rat and sheep orthologs. The encoded protein interacts with IRS1 protein, suggesting a role in regulating insulin sensitivity. Several transcript variants that differ in the 5' UTR but that encode the same protein have been identified for this gene. [provided by RefSeq]

tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, zeta polypeptide

Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways (PubMed:14578935, PubMed:15071501, PubMed:15644438, PubMed:16376338, PubMed:16959763, PubMed:31024343, PubMed:9360956).
Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif (PubMed:35662396).
Binding generally results in the modulation of the activity of the binding partner (PubMed:35662396).
Promotes cytosolic retention and inactivation of TFEB transcription factor by binding to phosphorylated TFEB (PubMed:35662396).
Induces ARHGEF7 activity on RAC1 as well as lamellipodia and membrane ruffle formation (PubMed:16959763).
In neurons, regulates spine maturation through the modulation of ARHGEF7 activity (By similarity).

Located to stage I to stage IV melanosomes.

The delta, brain-specific form differs from the zeta form in being phosphorylated (Probable). Phosphorylation on Ser-184 by MAPK8; promotes dissociation of BAX and translocation of BAX to mitochondria (PubMed:15071501, PubMed:15696159).
Phosphorylation on Thr-232; inhibits binding of RAF1 (PubMed:9360956).
Phosphorylated on Ser-58 by PKA and protein kinase C delta type catalytic subunit in a sphingosine-dependent fashion (PubMed:11956222, PubMed:12865427, PubMed:15883165, PubMed:16376338).
Phosphorylation on Ser-58 by PKA; disrupts homodimerization and heterodimerization with YHAE and TP53 (PubMed:11956222, PubMed:12865427, PubMed:15883165, PubMed:16376338).
