What pLDDT means and how to read it

Function

Guanine nucleotide-binding protein that plays a crucial role in the cellular response to amino acid availability through regulation of the mTORC1 signaling cascade (PubMed:20381137, PubMed:24095279, PubMed:25936802, PubMed:31601708, PubMed:31601764, PubMed:38103557). Forms heterodimeric Rag complexes with RagC/RRAGC or RagD/RRAGD and cycles between an inactive GDP-bound and an active GTP-bound form: RagA/RRAGA is in its active form when GTP-bound RagA/RRAGA forms a complex with GDP-bound RagC/RRAGC (or RagD/RRAGD) and in an inactive form when GDP-bound RagA/RRAGA heterodimerizes with GTP-bound RagC/RRAGC (or RagD/RRAGD) (PubMed:20381137, PubMed:24095279, PubMed:25936802, PubMed:31601708,…

Subunit structure

Can occur as a homodimer or as a heterodimer with RRAGC or RRAGD in a sequence-independent manner; heterodimerization stabilizes proteins of the heterodimer (PubMed:11073942, PubMed:20381137, PubMed:31601708, PubMed:31601764, PubMed:32868926). The GTP-bound form of RRAGA (in complex with the GDP-bound form of RRAGC or RRAGD) interacts with RPTOR, thereby promoting recruitment of mTORC1 to the…
