Description

NECL2 (Nectin-like protein 2), also known as IgSF4 and CADM1 (cell adhesion molecule 1), is a single pass type I transmembrane glycoprotein that belongs to the Nectin family of the Ig (immunoglobulin) superfamily.  Most Nectin family members function as cell adhesion molecules (CAMs) located on the cell surface and involved with the binding with other cells or with the extracellular matrix (ECM). Like other Nectin members, NECL2 contains 1 Ig-like V-type domain and 2 Ig-like C2-type domains in the extracellular region that mediates calcium-independent adhesive interactions, either homophilic or heterophilic with CRTAM (class I­restricted T cell­associated molecule), Necl­1 or Nectin­3. NECL2 is found on mast cells, neurons, and dendritic cells. Necl2 is also known s TSLC­1 (tumor suppressor in lung cancer­1).  It is downregulated in non­small cell lung cancer. This may allow evasion of antitumor responses, as NECL2 interacts with CRTAM on activated NK and CD8+ T cells and stimulates cytotoxicity. NECL2 binds homotypically across synaptic clefts and promotes formation of neural cell synapses. Expression on mast cells allows attachment to neurites and fibroblasts. NECL2 contains a cytoplasmic domain with protein 4.1 and PDZ domain binding sites, allowing connections to adaptor molecules that are critical for synaptogenesis.
