Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using PCSK7 (D4I5G) Rabbit mAb.



Immunoprecipitation of PCSK7 protein from HT-29 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is PCSK7 (D4I5G) Rabbit mAb. Western blot analysis was performed using PCSK7 (D4I5G) Rabbit mAb.


PCSK7 (PC7) is a member of the subtilisin-like proprotein convertase family (1,2). Like other members of the family, the protein cleaves precursors at basic amino acids within the motif Arg/Lys-Xn-Arg (cleavage site) (n=2 or 4). PC7 was reported to be localized in the trans-golgi network and at the cell surface membrane, as well as in membrane internalized recycling vesicles (2,3). One function of PCSK7 is its critical role in growth factors processing, for example proEGF to EGF, proVEGF-C to VEGF-C, and BDNF neuropeptide maturation. PCSK7 is also involved in transferrin receptor shedding to regulate ion homeostasis (7,8) and MHC class I stability to regulate antigen presentation in the immunoresponse process (9).
