What pLDDT means and how to read it

Function

Non-catalytic component of the C9orf72-SMCR8 complex, a complex that has guanine nucleotide exchange factor (GEF) activity and regulates autophagy (PubMed:27103069, PubMed:27193190, PubMed:27617292, PubMed:28195531). The C9orf72-SMCR8 complex promotes the exchange of GDP to GTP, converting inactive GDP-bound RAB8A and RAB39B into their active GTP-bound form, thereby promoting autophagosome maturation (PubMed:27103069). As part of the C9orf72-SMCR8 complex, stimulates RAB8A and RAB11A GTPase activity in vitro, however WDR42 is shown not be an essential complex component for this function (PubMed:32303654). The C9orf72-SMCR8 complex also acts as a negative regulator of autophagy initiation…

Subunit structure

Component of the C9orf72-SMCR8 complex, at least composed of C9orf72, SMCR8 and WDR41 (PubMed:27103069, PubMed:27193190, PubMed:27617292, PubMed:28195531, PubMed:32303654). The complex is formed of two protomers, each individually consisting of one molecule each of C9orf72, SMCR8 and WDR41 (PubMed:32303654). The protomers homodimerize via an interaction between C9orf72 (via C-terminus) and SMCR8…
