PCDH15 Edit Wikipedia article
Protocadherin-15 is a protein that in humans is encoded by the PCDH15 gene.[5][6][7]
Function
This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. The protein product of this gene consists of a signal peptide, 11 extracellular calcium-binding domains, a transmembrane domain and a unique cytoplasmic domain. It plays an essential role in maintenance of normal retinal and cochlear function.[7] It is thought to interact with CDH23 to form tip-link filaments.[8]
Clinical significance
Mutations in this gene have been associated with hearing loss, which is consistent with its location at the Usher syndrome type 1F (USH1F) critical region on chromosome 10.[7] Variation within it has also been found to be associated with normal differences in human facial appearance.[9]

Extracellular Cadherin domain Provide feedback
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].

Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the ECD domain has been found. There are 8 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
