Descripción

Descripción general

DnaJ homolog subfamily C member 13 (UniProt O75165; also known as Required for receptor-mediated endocytosis 8, RME-8) is encoded by the DNAJC13 (also known as KIAA0678, PARK21, RME8) gene (Gene ID 23317) in human. Originally identified as a C. elegans protein involved in mediating endocytosis, , receptor-mediated endocytosis 8 (RME-8) is a member of the DNAJ family of proteins implicated in regulating protein folding through associated chaperones. RME-8 is shown to interact with Hsc70/HSP-1 and sorting nexin 1 (SNX-1), loss of RME-8, SNX-1 or Hsc70 affects retrograde trafficking at the early endosomes-TGN interface. In addition, RME-8 is demonstrated to coordinate the function of the WASH complex and the retromer SNX dimer. The pentameric WASH complex is comprised of WASH1, strumpellin, SWIP (strumpellin- and wash-interacting protein), FAM21, and CCDC53. RME-8 N-terminal J region (a.a. 1-453) involved in membrane association is found to be involved in establishing interaction with the first third of FAM21 tail domain. WASH complex is responsible for the generation of branched actin networks on endosomes and the creation of microdomains into which specific cargoes can be concentrated. Loss of RME-8 function results in a profound endosomal tubulation, more extensive than the endosomal tubulation phenotype resulted from loss of the WASH complex.

Western Blotting Analysis: A representative lot detected RME-8 associated with the 20,000 xg pelleted insoluble fraction from the HEPES buffer homogenates of human skin fibroblast MCH46, breast epithelial MCF10A, and embryonic kidney HEK293T cells (BT-474, HeLa, SK-BR-3) cells (Ioannou, M.S., et al.

Immunocytochemistry Analysis: A representative deteced a reduced RME-8 immunoreactivity in HeLa cells transfected with shRNA targeting either RME-8 or Spastin (Freeman, C.L., et al. (2014). J. Cell Sci. 127(Pt 9):2053-2070).

Immunocytochemistry Analysis: A representative lot detected puntate endosomal RME-8 immunoreactivity by fluorescent immunocytochemistry staining of 2% paraformaldehyde-fixed, 0.2% Triton X-100-permeabilized COS-7 cells. LIttle RME-8 immunoreactivity was seen associated with TGN, lysosome, or plasma membrane, RME-8 shRNA transfection greately abolished cellular immunostaining (Girard, M., et al. (2005). J. Biol. Chem. 280(48):40135-40143).

Western Blotting Analysis: A representative lot detected the presence of RME-8 in WASH complex immunoprecipitated from HeLa cells (BT-474, HeLa, SK-BR-3) cells (Freeman, C.L., et al. (2014). J. Cell Sci. 127(Pt 9):2053-2070).

Western Blotting Analysis: Representative lots detected a greatly reduced ~200 kDa target band in lysates from RME-8 shRNA-transfected monkey (COS-7) and human (BT-474, HeLa, SK-BR-3) cells (Freeman, C.L., et al. (2014). J. Cell Sci. 127(Pt 9):2053-2070; Girard, M., and McPherson, P.S. (2008). FEBS Lett. 582(6):961-966; Girard, M., et al. (2005). J. Biol. Chem. 280(48):40135-40143).

Western Blotting Analysis: A representative lot detected the ~200 kDa RME-8 target band in postnuclear extracts from multiple rat tissues as well as from human, monkey, mouse, and rat cell lines. RME-8 was found enriched in rat kidney tissue-derived subcellular fractions representing microsomes and clathrin-coated vesicles (CCVs), but not cytosol or plasma membrane (Girard, M., et al. (2005). J. Biol. Chem. 280(48):40135-40143).
