A mammalian ER-localized transmembrane J-protein, DNAJB12, cooperates with Hsc70, a cytosolic Hsp70 family member, to promote the ERAD of misfolded membrane proteins. Mammalian genomes have another J-protein called DNAJB14 that shows a high sequence similarity to DNAJB12. DNAJB14 (DnaJ Heat Shock Protein Family (Hsp40) Member B14) is located on human chromosome 4q2. DNAJB14 is associated with some diseases, such as Erythema Infectiosum. An important paralog of this gene is DNAJB12. Like DNAJB12, DNAJB14 is an ER-localized, single membrane-spanning J-protein with its J-domain facing the cytosol. DNAJB14 can also specifically bind Hsc70 via its J-domain to recruit this chaperone to ER membrane. DNAJB14 can enhance the degradation of a misfolded membrane protein using the ubiquitin-proteasome system.
