Summaries for DENND1B Gene

Entrez Gene Summary for DENND1B Gene

  • Clathrin (see MIM 118955)-mediated endocytosis is a major mechanism for internalization of proteins and lipids. Members of the connecdenn family, such as DENND1B, function as guanine nucleotide exchange factors (GEFs) for the early endosomal small GTPase RAB35 (MIM 604199) and bind to clathrin and clathrin adaptor protein-2 (AP2; see MIM 601024). Thus, connecdenns link RAB35 activation with the clathrin machinery (Marat and McPherson, 2010 [PubMed 20154091]).[supplied by OMIM, Nov 2010]

GeneCards Summary for DENND1B Gene

DENND1B (DENN Domain Containing 1B) is a Protein Coding gene. Diseases associated with DENND1B include Asthma and Interleukin-7 Receptor Alpha Deficiency. GO annotations related to this gene include Rab guanyl-nucleotide exchange factor activity. An important paralog of this gene is DENND1A.

UniProtKB/Swiss-Prot for DENND1B Gene

  • Guanine nucleotide exchange factor (GEF) for RAB35 that acts as a regulator of T-cell receptor (TCR) internalization in TH2 cells (PubMed:20154091, PubMed:20937701, PubMed:24520163, PubMed:26774822). Acts by promoting the exchange of GDP to GTP, converting inactive GDP-bound RAB35 into its active GTP-bound form (PubMed:20154091, PubMed:20937701). Plays a role in clathrin-mediated endocytosis (PubMed:20154091). Controls cytokine production in TH2 lymphocytes by controlling the rate of TCR internalization and routing to endosomes: acts by mediating clathrin-mediated endocytosis of TCR via its interaction with the adapter protein complex 2 (AP-2) and GEF activity (PubMed:26774822). Dysregulation leads to impaired TCR down-modulation and recycling, affecting cytokine production in TH2 cells (PubMed:26774822).

DEN1B_HUMAN
  • Asthma (ASTHMA) [MIM:600807]: The most common chronic disease affecting children and young adults. It is a complex genetic disorder with a heterogeneous phenotype, largely attributed to the interactions among many genes and between these genes and the environment. It is characterized by recurrent attacks of paroxysmal dyspnea, with wheezing due to spasmodic contraction of the bronchi. {ECO:0000269 PubMed:20032318, ECO:0000269 PubMed:26774822}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Asthma susceptibility is probably caused by decreased TCR down-modulation and recycling in TH2 cells, causing prolonged TCR signaling and increased cytokine production in TH2 lymphocytes (PubMed:26774822). {ECO:0000269 PubMed:26774822}.
