Recombinant Human SPESP1 (C-6His)

Description

EnkiLife provides the Recombinant Human SPESP1 (C-6His) protein,aslo know as Sperm Equatorial Segment Protein 1,ESP,Equatorial Segment Protein,SP-ESP,Glycosylated 38 kDa Sperm Protein C-7/8,SPESP1, which features high purity, high activity, and high stability. It can be applied in scientific research, biopharmaceuticals, and other fields.Purity:Greater than 95% as determined by reducing SDS-PAGE;Endotoxin Level:<1 EU/µg as determined by LAL test.;Construction:Recombinant Human Sperm Equatorial Segment Protein 1 is produced by our Mammalian expression system and the target gene encoding Tyr20-Tyr350 is expressed with a 6His tag at the C-terminus.Accession:Q6UW49. Expression Host:Human Cells.Species:Human.Predicted Molecular Mass:37.9 KDa. Background:Sperm Equatorial Segment Protein 1 (SPESP1) is a member of the SPESP1 family. SPESP1 is highly expressed in the testis, where it is localized to the acrosome of postmeiotic stages of spermiogenesis; it is expressed at lower levels in the placenta and fetal lung. SPESP1 is involved in the multicellular organisimal development. Disruption of SPESP1 leads to abnormal distribution of sperm proteins resulting in a detached membrane from the equatorial segment and less fertile sperm. SPESP1 may interact with IZUMO1 and MN9 antigen and it contains an N-glycosylation site as well as several cAMP-dependent kinase, protein kinase C, and casein kinase II consensus phosphorylation sites.
