Literature-anchored findings (GeneRIF, showing 5)

  • TSPAN33 is overexpressed in activated and malignant B cells. (PMID:24211713)
  • The results suggest that TSPAN33 represents a new control element in the development of inflammation by macrophages that could constitute a potential therapeutic target. (PMID:27574297)
  • Data show that tetraspanin 33 (tspan33) is an early activation marker, and that disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) protein expression does not correlate with Tspan33 expression in B cells. (PMID:28449222)
  • Tetraspanin 33 (TSPAN33) regulates endocytosis and migration of human B lymphocytes by affecting the tension of the plasma membrane. (PMID:31958362)
  • Cooperative binding of the tandem WW domains of PLEKHA7 to PDZD11 promotes conformation-dependent interaction with tetraspanin 33. (PMID:32371390)

Function. Part of TspanC8 subgroup, composed of 6 members that interact with the transmembrane metalloprotease ADAM10. This interaction is required for ADAM10 exit from the endoplasmic reticulum and for enzymatic maturation and trafficking to the cell surface as well as substrate specificity. Different TspanC8/ADAM10 complexes have distinct substrates. Plays an important role in normal erythropoiesis. It has a role in the differentiation of erythroid progenitors. Negatively regulates ligand-induced Notch activity probably by regulating ADAM10 activity. Mediates docking of ADAM10 to zonula adherens by interacting with ADAM10 and, in a PDZD11-dependent manner, with the zonula adherens protein PLEKHA7.

Subunit / interactions. Homodimer; disulfide-linked. Interacts (via extracellular domain) with ADAM10 (via extracellular domain). Interacts (via cytoplasmic domain) with PLEKHA7 (via WW domains); the interaction is dependent on PDZD11 being bound to PLEKHA7 and facilitates the docking of ADAM10 to zonula adherens.

Subcellular location. Cell membrane. Cell junction. Adherens junction. Cytoplasm.

Tissue specificity. Predominantly expressed in erythroblasts.

Similarity. Belongs to the tetraspanin (TM4SF) family.
