Involvement in diseasei

Ectodermal dysplasia, Margarita Island type (EDMI)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. It is a syndrome characterized by the association of cleft lip/palate, ectodermal dysplasia (sparse short and dry scalp hair, sparse eyebrows and eyelashes), and partial syndactyly of the fingers and/or toes. Two thirds of the patients do not manifest oral cleft but present with abnormal teeth and nails.
See also OMIM:225060
Non-syndromic orofacial cleft 7 (OFC7)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA birth defect consisting of cleft lips with or without cleft palate. Cleft lips are associated with cleft palate in two-third of cases. A cleft lip can occur on one or both sides and range in severity from a simple notch in the upper lip to a complete opening in the lip extending into the floor of the nostril and involving the upper gum.

Interactioni

Subunit structurei

Interacts (via Ig-like C2-type domain 2) with FGFR1, FGFR2 and FGFR3 (By similarity). Cis- and trans-homodimer. Can form trans-heterodimers with NECTIN3 and with NECTIN4. Interaction between NECTIN1 and NECTIN3 on the pre- and postsynaptic sites, respectively, initiates the formation of puncta adherentia junctions between axons and dendrites. Interacts (via cytoplasmic domain) with MLLT4/afadin (via PDZ domain); this interaction recruits NECTIN1 to cadherin-based adherens junctions and provides a connection with the actin cytoskeleton. Interacts with integrin alphaV/beta3.By similarity4 Publications
(Microbial infection) Interacts with herpes simplex virus 1/HHV-1, herpes simplex virus 2/HHV-2, and pseudorabies virus/PRV envelope glycoprotein D (PubMed:21980294, PubMed:22146396, PubMed:9696799, PubMed:9657005).4 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
