Data suggest that activation of the metalloproteinase ADAM10 by signal peptide peptidase-like 3 (SPPL3) triggered by mutant BRAF(V600E) was a critical transformation event.

Authors demonstrate that SPPL3 alters the pattern of cellular N-glycosylation by triggering the proteolytic release of active site-containing ectodomains of glycosidases and glycosyltransferases.
Title: Shedding of glycan-modifying enzymes by signal peptide peptidase-like 3 (SPPL3) regulates cellular N-glycosylation.
SPPL3 substrates identified on a proteome-wide scale in human and murine cells include numerous glycan-modifying enzymes residing in the Golgi network and implicated in distinct glycosylation pathways, including N-glycosylation, mucin-type O-glycosylation, O-mannosylation and glycosaminoglycan biosynthesis.
Title: Secretome analysis identifies novel signal Peptide peptidase-like 3 (Sppl3) substrates and reveals a role of Sppl3 in multiple Golgi glycosylation pathways.
SPPL3 cleaves Golgi type II membrane proteins leading to their secretion. SPPL3 substrates include Golgi glycosyltransferases MGAT5, B4GALT1, and B3GNT1. By facilitating disengagement of these glycosyltransferases from their membrane anchors, SPPL3 causes their premature secretion and consequently orchestrates the extent of N-glycosylation on human and murine cells.

human SPPL3 is the first GxGD-type aspartyl protease shown to be capable of acting like a sheddase, similar to members of the rhomboid family, which belong to the class of intramembrane-cleaving serine proteases.
Title: Foamy virus envelope protein is a substrate for signal peptide peptidase-like 3 (SPPL3).
SPPL2b is targeted through the secretory pathway to endosomes/lysosomes, whereas SPP and SPPL3 are restricted to the ER.
Title: Differential localization and identification of a critical aspartate suggest non-redundant proteolytic functions of the presenilin homologues SPPL2b and SPPL3.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
