What pLDDT means and how to read it

Function

Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase (PubMed:10656250, PubMed:10677483, PubMed:20354142). Cleaves CHL1 (By similarity)

Subunit structure

Monomer. Interacts (via DXXLL motif) with GGA1, GGA2 and GGA3 (via their VHS domain); the interaction highly increases when BACE1 is phosphorylated at Ser-498 (PubMed:14567678, PubMed:15886016). Interacts with RTN1; RTN2; RTN3 and RTN4; the interaction leads to inhibition of amyloid precursor protein processing (PubMed:15286784, PubMed:16965550, PubMed:16979658). Interacts with SNX6…
