Biochemistry. Abbr. of Heat-Shock Cognate 70 Protein.
A constitutively expressed protein of the HSP70 heat-shock proteins family. Hsc70 is involved in a range of cellular processes, such as protein folding, translocation across membranes and the assembly or disassembly of protein complexes. Hsc70 has 85% identity with Hsp70. Therefore it is classified in the HSP70 family while it is constitutively expressed in contrast to the heat-inducible heat-shock proteins.
