SEQUENCE SIMILARITIES

Belongs to the NOTCH family.

TISSUE SPECIFICITY

Highly expressed in the heart, moderately in the lung and placenta and at low levels in the liver, skeletal muscle, kidney, pancreas, spleen, lymph node, thymus, bone marrow and fetal liver. No expression was seen in adult brain or peripheral blood leukocytes.

POST-TRANSLATIONAL MODIFICATION

Synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by a furin-like convertase in the trans-Golgi network before it reaches the plasma membrane to yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved by TNF-alpha converting enzyme (TACE) to yield a membrane-associated intermediate fragment called notch extracellular truncation (NEXT). This fragment is then cleaved by presenilin dependent gamma-secretase to release a notch-derived peptide containing the intracellular domain (NICD) from the membrane (By similarity).; Phosphorylated.

SUBCELLULAR LOCATION

Cell membrane, Nucleus.

FUNCTION

Neurogenic locus notch homolog 4 (Notch 4) is a protein that in humans is encoded by the NOTCH4 gene located on chromosome 6. Notch protein family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling pathway is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells. In Drosophila, notch interacts with its cell-bound ligands (delta and serrate), and establishes an intercellular signaling pathway that then plays a key role in development. Homologues of the notch-ligands have also been identified in humans, but precise interactions between these ligands and the human notch homologues remain to be determined. The notch protein is cleaved in the trans-Golgi network, and then presented on the cell surface as a heterodimer. The protein functions as a receptor for membrane bound ligands, and may play a role in vascular, renal, and hepatic development.
