DLL1

Disease related genes, Human disease related genes

Intracellular, Membrane (different isoforms)

Cell type enhanced (Adipocytes, Basal squamous epithelial cells, Intestinal goblet cells, Basal keratinocytes, Enteroendocrine cells)

Immune cell enriched (NK-cell)

Cell line enhanced (HaCaT, HBEC3-KT, NB-4, THP-1)

Homodimer. Interacts with TJP1. Interacts with MAGI1 (via PDZ domain); forms a complex with CTNNB1 and CDH2 and promotes recruitment to the adherens junction and stabilization on the cell surface. Interacts with PSEN1; undergoes a presenilin-dependent gamma-secretase cleavage that releases a Dll1-intracellular form. Interacts with MFAP5. Interacts with MIB1. Interacts with NEURL1B; leads to ubiquitination. Interacts with NEURL1 (By similarity). Interacts with SYNJ2BP; enhances DLL1 protein stability, and promotes Notch signaling in endothelial cells (PubMed:24025447). Interacts with MAGI1, MAGI2, MAGI3 and MPDZ (PubMed:15509766). Interacts (via ubiquitin) with EPN1 (via IUM domain); binding with NOTCH1 attached to neighboring cell, promotes ligand ubiquitination and EPN1 interaction, leading to NECD transendocytosis and Notch signaling. Interacts with NOTCH1 (By similarity) (PubMed:15509766, PubMed:24025447). Interacts with NOTCH2NLB; leading to promote Notch signaling pathway in a cell-autonomous manner through inhibition of cis DLL1-NOTCH2 interactions (PubMed:29856955).
