背景资料
ST13(Suppression of Tumorigenicity 13), also known as P48 or HIP, is a protein that in humans is encoded by the ST13 gene. ST13 is an abundant, highly conserved protein that binds the major cytosolic chaperones heat-shock protein 70-kD(HSP70) and HSP90 during an intermediate stage of steroid receptor assembly, but is absent from the mature receptor complex. Zhang et al.(1998) mapped the ST13 gene to chromosome 22q13 by fluorescence in situ hybridization. They noted that colorectal, breast, and ovarian carcinomas frequently show loss of heterozygosity at this site. Using a yeast 2-hybrid assay, Hohfeld et al.(1995) showed that rat Hip bound Hsc70(HSPA8). One Hip oligomer bound the ATPase domains of at least 2 Hsc70 molecules, and binding was dependent on activation of the Hsc70 ATPase by Hsp40(DNAJB1). Hip stabilized the ADP-bound form of Hsc70, which had a high affinity for a test protein substrate. Hohfeld et al.(1995) concluded that HIP contributes to interactions of HSC70 with target proteins through its own chaperone activity.
