A COMPARATIVE IN SILICO STUDY FINDS A FUNCTIONAL CO-RELATION BETWEEN HUMAN HSP7C AND PLANT PROTEIN

A bioinformatics finding shows that numerous human heat shock proteins (HSPs) homologues are common in plants. Human heat shock proteins (HSPs), which are expressed to higher temperature or other stress, have chaperone activity belong to four conserved classes: HSP60, HSP70, HSP90 and HSP100. Bioinformatics blast search reveals that each of the human HSP classes possess a number of plant homologues. The closest identified plant homologue of human HSP_7C is a protein of unknown function (NCBI Accession XP_002332067) derived from Populus trichocarpa. In silico comparative studies have showed invigorating similarity of human HSP_7C and the designated protein of Populus trichocarpa. Secondary and three-dimensional (3D) structure analysis of the predicted plant protein strongly supports its functional relationship to the class of human HSP70.
