What pLDDT means and how to read it

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. Negative regulator of osteogenesis. Blocks the nuclear translocation of the phosphorylated form (by AKT1) of SRPK2 and antagonizes its stimulatory effect on cyclin D1 expression resulting in blockage of neuronal apoptosis elicited by SRPK2. Negative regulator of signaling cascades that mediate activation of MAP kinases via AKAP13

Subunit structure

Homodimer (PubMed:17717073). Forms heterodimers with SFN, YWHAG or YWHAQ (By similarity). Interacts with SAMSN1 and PRKCE (By similarity). Interacts with AKAP13 (PubMed:21224381). Interacts with SSH1 and TORC2/CRTC2 (PubMed:15159416, PubMed:15454081). Interacts with ABL1; the interaction results in cytoplasmic location of ABL1 and inhibition of cABL-mediated apoptosis (PubMed:15696159).…
