| Description | Scavenger receptor A5 (SCARA5; also known as testis expressed scavenger receptor Tesr) is a Class A scavenger receptor that is related to CL-P1, MARCO, SCARA3, and SR-A1. All are type II transmembrane proteins that contain a collagenous stalk (1-3). Mature mouse SCARA5 consists of a 60 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 410 aa C-terminal extracellular domain (ECD) that contains a coiled-coil, a collagen-like, and a scavenger receptor cysteine-rich (SRCR) region (4, 5). Within the ECD, mouse SCARA5 shares 87% and 98% aa sequence identity with human and rat SCARA5, respectively. It shares 24%-29% aa sequence identity with CL-P1, MARCO, SCARA3, and SR-A1. Alternative splicing generates one isoform that lacks the SRCR domain and a second that additionally lacks the cytoplasmic and transmembrane regions. SCARA5 is a cell surface disulfide-linked homotrimer of > 250kD (5). It is highly expressed in testicular Sertoli and germ cells and more weakly in the epithelia of other tissues (4, 5). During mouse development, SCARA5 expression is attenuated in female embryos at the time of sex determination, whereas it is maintained in the developing testis (4). SCARA5 is re-expressed in the adult ovary (4). SCARA5 binds heat-killed bacterial particles but not yeast particles or modified LDL (5). A DNA sequence encoding the extracellular domain of mouse SCARA5 (Arg 83-Pro 491; Accession # Q8K299) was fused with a 6x histidine tag at the N-terminus and expressed in Chinese Hamster Ovary cells. Calculated molecular mass of 45.5kD. As a result of glycosylation, the recombinant protein migrates as an ~ 60-90kD protein in SDS-PAGE under reducing conditions. Activity: Measured by its ability to bind Fluorescein conjugated S. aureus Bioparticles. Storage and Stability: Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile PBS and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | ||
