Stable Association of hsp90 and p23, but Not hsp70, with Active Human Telomerase

Abstract excerpt

The ribonucleoprotein telomerase holoenzyme is minimally composed of a catalytic subunit, hTERT, and its associated template RNA component, hTR. We have previously found two additional components of the telomerase holoenzyme, the chaperones p23 and heat shock protein (hsp) 90, both of which are required for efficient telomerase assembly in vitro and in vivo. Both hsp90 and p23 bind specifically to hTERT and...
