General annotation (Comments)

Function

Component of the epithelial apical junction complex that is essential for the tight junction integrity. Proposed to function as a homophilic cell adhesion molecule. Recruits MPDZ to intercellular contact sites. Probably involved in transepithelial migration of polymorphonuclear leukocytes (PMN) through adhesive interactions with AMICA1/JAML located in the plasma membrane of PMN By similarity. Ref.2 Ref.3 Ref.6

In vitro, acts as a receptor for group B coxsackieviruses and subgroup C of adenoviruses (AD2 and AD5). Ref.2 Ref.3 Ref.6

Subunit structure

Monomer. Probably homodimer formed by 2 molecules on adjacent cells. Interacts with LNX, MPDZ, BAIAP1, DLG4, PRKCABP, TJP1 and CTNNB1 By similarity.

Subcellular location

Isoform 1: Cell membrane; Single-pass type I membrane protein By similarity. Cell junctionadherens junction By similarity. Cell junctiontight junction By similarity. Basolateral cell membrane; Single-pass type I membrane protein By similarity. Note: Localized at the intercellular contacts. In epithelial cells localizes to the apical junction complex composed of tight and adherens junctions. In airway epithelial cells localized to basolateral membrane but not to apical surface By similarity. Ref.6 Ref.8

Isoform 2: Cell membrane; Single-pass type I membrane protein By similarity. Cell junctionadherens junction By similarity. Cell junctiontight junction By similarity. Basolateral cell membrane; Single-pass type I membrane protein By similarity. Note: Localized at the intercellular contacts. In epithelial cells localizes to the apical junction complex composed of tight and adherens junctions. In airway epithelial cells localized to basolateral membrane but not to apical surface By similarity. Ref.6 Ref.8

Isoform 3: Secreted By similarity Ref.6 Ref.8.

Tissue specificity

Expressed in liver, kidney, heart, lung, and brain. In skeletal muscle is found at the neuromuscular junction. In cardiac muscle, isoform 1 and isoform 2 are found at intercalated disks. Ref.1 Ref.6 Ref.7 Ref.8

Developmental stage

Expression starts in the embryonic ectoderm in the uterus on E6.5. Then it is strongly expressed in the neuroepithelium of the neural tube, the developing brain and the spinal cord from E8.5 to postnatal day 7 (P7), in the cranial motor nerves from E9.5 to E11.5, and in the optic nerve from E13.5 to P7. Expression increases until perinatal period and decreases postnatally. Expressed in the immature neuroepithelium including progenitor cells it still occurs in a few proliferating cells of the hippocampal dentate gyrus, the subventricular zone of the lateral ventricles, and the rostral migratory stream over P21. Also expressed in heart, kidney and liver of newborn mice. Ref.6 Ref.7

Domain

The Ig-like C2-type 1 domain mediates homodimerization and interaction with AMICA1/JAML.

The PDZ-binding motif mediates interaction with MPDZ and BAIAP1 By similarity.

Post-translational modification

Palmitoylated on Cys-259 and/or Cys-260; required for proper localization to the plasma membrane By similarity.

Sequence similarities

Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
