Protein Construction: A DNA sequence encoding the mouse CRELD1 (NP_598691.1) (Met1-Glu362) was expressed with a C-terminal polyhistidine tag.
Stability and Storage: Lyophilized proteins are stable for up to 12 months when stored at -20 to -80?C. Reconstituted protein solution can be stored at 4-8? for 2-7 days. Aliquots of reconstituted samples are stable at < -20? for 3 months.
FormulationLyophilized from sterile PBS, pH 7.4
Background:CRELD1 is a transmembrane glycoprotein. Epidermal growth factor(EGF)like domain exists in CRELD1. EGF-like repeats are a class of cysteine-rich domains that mediate interactions between proteins of diverse function. EGF domains are found in proteins that are either completely secreted or have transmembrane regions that tether the protein to the cell surface. CRELD1 contains a 333 amino acid acid (aa) extracellular domain (ECD), two tandem transmembrane segments, and a second ECD of 15 aa. Defects in CRELD1 may cause susceptibility to atrioventricular septal defect type 2 which results in a persistent common atrioventricular canal.
