What pLDDT means and how to read it

Function

Palmitoyltransferase that catalyzes the addition of palmitate onto various protein substrates and is involved in a variety of cellular processes (PubMed:15489887, PubMed:15603740, PubMed:24705354, PubMed:27911442, PubMed:28757145). Has no stringent fatty acid selectivity and in addition to palmitate can also transfer onto target proteins myristate from tetradecanoyl-CoA and stearate from octadecanoyl-CoA (By similarity). Palmitoyltransferase specific for a subset of neuronal proteins, including SNAP25, DLG4/PSD95, GAD2, SYT1 and HTT (PubMed:15489887, PubMed:15603740, PubMed:19139280, PubMed:28757145). Also palmitoylates neuronal protein GPM6A as well as SPRED1 and SPRED3 (PubMed:24705354).…

Subunit structure

Interacts (via ANK repeats) with numerous proteins (via the consensus sequence motif [VIAP]-[VIT]-x-x-Q-P) (PubMed:28882895). Interacts (via ANK repeats) with CLIP3 (PubMed:26198635, PubMed:28882895). Interacts (via ANK repeats) with HTT; this interaction is inversely correlated to the length of the polyglutamine tract added to the huntingtin protein in Huntington disease (PubMed:12393793,…
