Collagen XIII alpha 1 in Human Placenta. Collagen XIII a1 was detected in immersion fixed paraffin-embedded sections of human placenta using Mouse Anti-Human Collagen XIII a1 Monoclonal Antibody (Catalog # MAB6346) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to basement membrane.

Background: Collagen XIII alpha 1

COL13A1 (collagen 13-alpha 1) is a 95 kDa member of the transmembrane group of the collagen family of proteins. It is a type II transmembrane glycoprotein that is expressed by multiple cell types, including fibroblasts, endothelial cells, and cardiac muscle. COL13A1 forms disulfide-linked homotrimers and participates in cell adhesion by binding to the Integrin alpha 1 subunit, Nidogen-2, and Fibronectin. Human COL13A1 is 717 amino acids (aa) in length. It has an N‑terminal 44 aa cytoplasmic region plus a 656 aa extracellular domain (ECD) (aa 62-717). The ECD contains four non-collagenous (NC) regions (aa 1‑121, aa 217-269, aa 442-463, and aa 700-717) interspersed among three collagenous (COL) domains (aa 122-216, aa 270-441, and aa 464-699). Multiple splice forms exist and typically involve deletions of 12-30 aa between aa 220-705. Proteolytic cleavage after Arg108 generates an 85-90 kDa soluble form. Over aa 109-668 (based on a human isoform [NP_542992} that shows a deletion of aa 239-260, aa 551-565, and aa 616-627), human COL13A1 shares 91% aa sequence identity with mouse COL13A1.
