This is an extracellular cadherin (EC) domain which can be found at the N-terminal region of Protocadherin 15 (Pcdh15). Pcdh15 features exceptionally long extracellular domains containing 11 ECs [1]. These repeats are structurally similar, but not identical in sequence, often featuring linkers with conserved calcium-binding sites that confer mechanical strength to them [2].	Domain
