14-3-3 eta 蛋白, Human (GST)

YWHAH proteins are adapter proteins in multiple signaling pathways that recognize phosphoserine or phosphothreonine motifs and regulate chaperone activity upon binding. It negatively regulates PDPK1 kinase activity and interacts with nuclear hormone receptors (AR, ESR1, ESR2, MC2R, NR3C1, NRIP1, PPARBP, THRA) and cofactors. 14-3-3 eta Protein, Human (GST) is the recombinant human-derived YWHAH protein, expressed by E. coli , with N-GST labeled tag.

YWHAH 蛋白作为衔接子发挥作用，参与广泛的一般和专门信号传导途径的调节，识别磷酸丝氨酸或磷酸苏氨酸基序以与众多伙伴结合。这种结合通常会导致相互作用伙伴的活性调节。YWHAH 负向调节 PDPK1 的激酶活性，并以同二聚体形式存在。它与多种核激素受体和辅助因子相互作用，包括 AR、ESR1、ESR2、MC2R、NR3C1、NRIP1、PPARBP 和 THRA。此外，它与磷酸化形式的 ABL1 相互作用，将其保留在细胞质中，并与 CDKN1B 相互作用较弱。其他相互作用涉及 ARHGEF28、CDK16、GAB2、KCNK18（以磷酸化依赖性方式）、SAMSN1、PDPK1 的“Ser-241”磷酸化形式、DAPK2 的“Thr-369”磷酸化形式、PI4KB、TBC1D22A、TBC1D22B、SLITRK1和 MEFV。这些不同的相互作用强调了 YWHAH 在各种细胞过程和信号通路中的多方面作用。
