    14-3-3 beta/YWHAB Background

    Gene Summary: YWHAB gene encodes a protein belonging to the 14-3-3 family of proteins, members of which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals. The encoded protein has been shown to interact with RAF1 and CDC25 phosphatases, suggesting that it may play a role in linking mitogenic signaling and the cell cycle machinery. Two transcript variants, which encode the same protein, have been identified for YWHAB gene. [provided by RefSeq, Jul 2008]
    General information above from NCBI
    Subunit structure: Homodimer. Interacts with SAMSN1 and PRKCE (By similarity). Interacts with SSH1 and TORC2/CRTC2. Interacts with ABL1; the interaction results in cytoplasmic location of ABL1 and inhibition of cABL-mediated apoptosis. Interacts with ROR2 (dimer); the interaction results in phosphorylation of YWHAB on tyrosine residues. Interacts with GAB2 and YAP1 (phosphorylated form). Interacts with the phosphorylated (by AKT1) form of SRPK2. Interacts with PKA-phosphorylated AANAT.
    Subcellular location: Cytoplasm. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
    Post-translational: The alpha, brain-specific form differs from the beta form in being phosphorylated (By similarity). Phosphorylated on Ser-60 by protein kinase C delta type catalytic subunit in a sphingosine- dependent fashion (By similarity).
    Isoform Short contains a N-acetylmethionine at position 1 (By similarity).
    Sequence similarity: Belongs to the 14-3-3 family.C

    14-3-3 beta / YWHAB is a member of the 14-3-3 proteins family. 14-3-3 proteins are a group of highly conserved proteins that are involved in many vital cellular processes such as metabolism, protein trafficking, signal transduction, apoptosis and cell cycle regulation. 14-3-3 proteins are mainly localized in the synapses and neuronal cytoplasm, and seven isoforms have been identified in mammals. This family of proteins was initially identified as adaptor proteins which bind to phosphoserine-containing motifs. Binding motifs and potential functions of 14-3-3 proteins are now recognized to have a wide range of functional relevance. 14-3-3 beta / YWHAB is found in both plants and mammals, and this protein is 100% identical to the mouse ortholog. 14-3-3 beta / YWHAB interacts with CDC25 phosphatases, RAF1 and IRS1 proteins, suggesting its role in diverse biochemical activities related to signal transduction, such as cell division and regulation of insulin sensitivity. 14-3-3 beta / YWHAB has also been implicated in the pathogenesis of small cell lung cancer. 14-3-3 beta / YWHAB binding negatively regulates RSK1 activity to maintain signal specificity and that association/dissociation of the 14-3-3beta-RSK1 complex is likely to be important for mitogen-mediated RSK1 activation.
