ANTH domain
Encyclopedia
The ANTH domain is a membrane binding domain that shows weak specificity for PtdIns(4,5)P2. It was found in AP180
(a.k.a. CALM) endocytotic accessory protein that has been implicated in the formation of clathrin-coated pits. The domain is involved in phosphatidylinositol 4,5-bisphosphate binding and is a universal adaptor for nucleation of clathrin coats.
Its structure is a solenoid of 9 helices. The PtdIns(4,5)P2 binding residues are spread over several helices at the tip of the structure. The PtdIns(4,5)P2 binding sequence is Kx9Kx(K/R)(H/Y).
An ANTH domain is also found in HIP1 and HIP1R
, and the PtdIns(4,5)P2 binding sequence is conserved. More information is found on endocytosis.org.
Ap180
AP180 is a protein that plays an important role in clathrin-mediated endocytosis of synaptic vesicles. It is capable of simultaneously binding both membrane lipids and clathrin and is therefore thought to recruit clathrin to the membrane of newly invaginating vesicles...
