Background

COL4A1 (collagen 4-alpha 1) is a calculated 185 kDa (ref. 1) member of the type IV collagen family. It is a secreted glycoprotein that is expressed by multiple cell types, including fibroblasts, keratinocytes, and endothelial cells. Two COL4A1 molecules interact with a 170 kDa alpha 2 chain to form a collagen IV triple helix. This helix further interacts with other helices to generate covalent oligomers that form a scaffold in the basement membrane. Mature human COL4A1 is 1642 amino acids (aa) in length (SwissProt #:P02462). It has an N-terminal “7S” proregion (aa 28-172), a central collagenous domain that contains multiple Gly-based repeats (aa 173-1440), and a C‑terminal domain that is proteolytically cleaved to generate a 25-28 kDa NC1 globular segment that has potent antiangiogenic activity (aa 1441-1669). Multiple splice forms exist. One shows a deletion of aa 499-849, a second shows a seven aa substitution for aa 513-1669, and a third shows a seven aa substitution for aa 958‑1669. Over aa 1441-1669, human COL4A1 shares 97% aa sequence identity to mouse COL4A1. AF6308 detects a 95 kDa band, endogenous COL4A1 by Westen blot in human placenta tissue sample, which is consistent with the current literature (ref. 1)
