https://en.wikipedia.org/wiki/PKD%20domain
PKD (Polycystic Kidney Disease) domain was first identified in the polycystic kidney disease protein, polycystin-1 (PKD1 gene), and contains an Ig-like fold consisting of a beta-sandwich of seven strands in two sheets with a Greek key topology, although some members have additional strands. Polycystin-1 is a large cel...
