Catalog# C683 Source Human Cells Description Recombinant Human Sperm Equatorial Segment Protein 1/SPESP1 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Tyr20-Tyr350) of Human SPESP1 fused with a polyhistidine tag at the C-terminus. Names Sperm Equatorial Segment Protein 1, ESP, Equatorial Segment Protein, SP-ESP, Glycosylated 38 kDa Sperm Protein C-7/8, SPESP1 Accession # Q6UW49 Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4 Shipping The product is shipped at ambient temperature. Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.Purity Greater than 95% as determined by reducing SDS-PAGE. Endotoxin Less than 0.1 ng/µg (1 IEU/µg).

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.
