Molecular chaperones guide peptide fold conformation throughout the lifetime of the peptide. One network of chaperone proteins involved in this activity, Heat shock protein 70s (Hsp70s), are well characterized at restoring peptide fold, utilizing J-domain containing protein chaperone cofactors to activate Hsp70 activity. DnaJ (Hsp40) homolog, subfamily C, member 25 (DNAJC25) is a class III transmembrane J-domain containing protein that to date is underrepresented in the literature. Recently, Hejtmancik et al. 2012. (unpublished data) have revealed that missense mutation to DNACJ25 at Pro90Leu (P90L) is strongly correlated with inherited Closed-Angle Glaucoma. Inherited mutations are well characterized for Open-Angle Glaucoma, however, prior to this finding, were unknown for Closed-Angle Glaucoma. In this report, analysis of the in vitro chaperone activity of DNAJC25 w+ and P90L is assessed utilizing an Hsp70 mediated Glucose-6-Phosphate Dehydrogenase refolding system, SWISS-MODEL predictions are performed for the J-domain structure of DNAJC25 w+ and P90L with consequent analysis of DNAJC25 Pro90 conservation relative to other type I, II, and III J-domain containing proteins. DNAJC25 P90L demonstrated decreased chaperone activity in vitro compared to w+ DNAJC25. / by Daniel C.
