What pLDDT means and how to read it

Function

Constitutively open nonselective divalent cation-conducting channels which mediate the influx of Ca(2+), Mg(2+), Mn(2+), Ba(2+), and Ni(2+) into the cytoplasm, leading to membrane depolarization. Impermeable to zinc ions. In addition, forms heteromultimeric ion channels with TRPM3 which are permeable for calcium and zinc ions. Plays an essential role for the depolarizing photoresponse of retinal ON bipolar cells (PubMed:19861548). In the dark, tonic release of glutamate activates the G protein-coupled receptor for glutamate (GRM6), its activation induces the release of G(o) and the beta-gamma G protein dimer. Both subunits can interact and inactivate the TRPM1 channel. A light onset,…

Subunit structure

Homodimer (PubMed:25112866). Interacts with TRPM3; the interaction results in the formation of a heteromultimeric cation channel complex that are functionally different from the homomeric channels (By similarity). Interacts with GPR179 (PubMed:24114537, PubMed:24790204). Associates with both guanine nucleotide-binding proteins G(o) and beta-gamma G protein dimer; implicated in directly…
