  Domain Name: HN_L-whirlin_R1_like
First harmonin_N_like domain (repeat 1) of the long isoform of whirlin, and related domains. This subgroup contains the first of two harmonin_N_like domains of the long isoform of whirlin, and related domains. Whirlin is a postsynaptic density-95/discs-large/ZO-1 (PDZ) domain-containing scaffold protein which binds various components of the Usher protein network of the inner ear and the retina: erythrocyte protein p55, usherin, VlGR1, and myosin XVa. The long isoform of whirlin contains two harmonin_N_like domains, and three PDZ protein-binding domains, PDZ1-3. This first harmonin_N_like domain precedes PDZ1, and is a putative protein-binding module based on its sequence similarity to the N-terminal domain of harmonin. This first harmonin_N_like domain has been assayed for interaction with the cytoplasmic domain of cadherin 23 (a component of the Usher network and an interacting partner of the harmonin N-domain), however no interaction could be detected. The short whirlin isoform, derived from an alternative start ATG, lacks this first harmonin_N_like domain. The short isoform has in common with the long isoform, the second harmonin_N_like domain (designated repeat 2, not present in this subgroup), and PDZ3.
No pairwise interactions are available for this conserved domain.

This domain occurred 1 times on human genes (3 proteins).

 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
