Welcome to HSPIR Database

HSPIR is a manually curated online database which provides comprehensive information on six major Heat Shock Proteins(HSPs) viz., sHsp (HSP20), Hsp40 (J-Proteins), Hsp70 (DnaK/Ssa), Hsp60 (Chaperonin), Hsp90 (HtpG) and Hsp100 (Clp). HSPs are highly conserved and ubiquitous group of proteins present in all living organisms. HSPs play a critical role in maintaining protein homeostasis by re-establishing functional native conformation of proteins during unfavourable conditions such as elevated temperatures and other stresses. HSPs inludes a vast repertoire of functions such as de novo protein folding, disaggregation and protein trafficking. This makes HSPs a valuable resource for researchers studying the protein folding and resistance and survival of pathogens. HSPs and their classification are further described here.
