Descripción

Descripción general

Cation-independent mannose-6-phosphate receptor (UniProt P11717; also known as 300 kDa mannose 6-phosphate receptor, CD222, CI Man-6-P receptor, CI-MPR, IGF-II receptor, Insulin-like growth factor 2 receptor, Insulin-like growth factor II receptor, M6P/IGF2 receptor, M6P/IGF2R, M6P-R, M6PR, MPR 300) is encoded by the IGF2R (also known as CIMPR, MPRI) gene (Gene ID 3482) in human. Mannose 6-phosphate (M6P) receptors (MPRs) mediate the delivery of newly synthesized, mannose 6-phosphate-bound lysosomal hydrolases from the secretory pathway to the endosomal system. MPRs bind lysosomal hydrolases in the trans-Golgi network (TGN) and unload the enzyme in the endosomal system. There exist a cation-independent CI-MPR (IGF2R) and a smaller CD-MPR that requires divalent cations for lysosomal hydrolases recognition. MPRs also undergo recycling between the endosomal system and the plasma membrane, where CI-MPR mediates the internalization of other ligands, including insulin-like growth factor II (IGF-II). CI-MPR/IGF2R is produced with a signal peptide (a.a. 1-40), the removal of which yields the mature receptor with a large lumenal/extracellular region (a.a. 41-2304), a transmembrane segment (a.a. 2305-2327), and a cytoplasmic domain (a.a. 2328-2491), The extracellular region is composed of 15 P-type carbohydrate recognition domains, also referred to as MRH (mannose 6-phosphate receptor homology) domains. Domains 3 and 9 bind M6P with high affinity and domain 5 binds M6P with weak affinity, while domain 11 binds IGF-II.

Especificidad

Clone 2C2 targets the extracellular (lumenal) domain of IGF-II receptor (MPR). Clone 2C2 competed against IGF-II for MPR binding without affecting MPR interaction with pentamannose 6-phosphate (PMP) or beta-hexosaminidase, nor MPR-mediated beta-hexosaminidase endocytosis (Braulke, T., et al. (1988). Biochem. Res. Commun. 150(3):1287-1293; Braulke, T., et al. (1987). J. Cell Biol.;104(6):1735-1742).

Inmunógeno

Epitope: Extracellular (lumenal) domain.

Recombinant full-length human MPR300/IGF-2R/CD222.

Aplicación

Affinity Binding Assay: Representative lots were labeled with 125I and employed to bind and assess IGF-II receptor (MPR) on the surface of human fibroblasts (van Rahden, V.A., et al. (2012). Hum. Mol. Genet. 21(23):5019-5038; Braulke, T., et al. (1987). J. Cell Biol.;104(6):1735-1742).
Affinity Binding Assay: A representative lot competed against IGF-II, but not pentamannose 6-phosphate (PMP), for binding immobilized IGF-II receptor (MPR) (Braulke, T., et al. (1988). Biochem. Res. Commun. 150(3):1287-1293).
Western Blotting Analysis: A representative lot was labeled with 125I and detected the ~300 kDa IGF-II receptor (MPR300) in lysates from HeLa cells and primary human macrophages (Pohl, S., et al. (2010). J. Biol. Chem. 285(31):23936-23944).
Immunohistochemistry Analysis: A representative lot detected hepatocyte membrane and cytoplasmic M6P/IGF-2R immunoreactivity in normal human liver frozen sections. A reduced immunostaining of hepatocytes restricted to the sinusoidal part of the cell membrane and an increased signals in perisinusoidal cells was seen in cirrhotic livers (Sedlaczek, N., et al. (2003). Br. J. Cancer. 88(5):733-739).
Immunocytochemistry Analysis: A representative lot immunostained late endosomes in 2% paraformaldehyde-fixed, 0.01% saponin-permeabilized human fibroblasts (Bakker, A.C., et al. (1997). J. Cell Sci. 110 (Pt 18):2227-2238).
