... have been found to inhibit Hsp association with STIP1 through binding of STIP1 tetratricopeptide repeat (TPR) domains, possibly regulating the chaperone cycle. Here, we investigated the molecular basis of S100A1 binding to STIP1. We show that three S100A1 dimers associate with one molecule of STIP1...

... glutamine-rich tetratricopeptide repeat (TPR)-containing protein (SGT). We found that GHR interacts with SGT. In vivo , both the precursor and the mature form of the receptor interacted with SGT. Inactivation of the ubiquitin-conjugating system did not affect the GHR–SGT interaction. Binding studies showed...

... identified. The brain-derived cDNAs coded for two related proteins that differ only slightly at their N-terminus, and exhibit 39.8% identity to human PEX5p. The shorter liver-derived cDNA coded for the C-terminal tetratricopeptide repeat-containing domain of the brain cDNA-encoded proteins. Since these three...
