Summary: This gene encodes a member of the cysteine peptidase family C13 that plays an important role in the endosome/lysosomal degradation system. The encoded inactive preproprotein undergoes autocatalytic removal of the C-terminal inhibitory propeptide to generate the active endopeptidase that cleaves protein substrates on the C-terminal side of asparagine residues. Mice lacking the encoded protein exhibit defects in the lysosomal processing of proteins resulting in their accumulation in the lysosomes, and develop symptoms resembling hemophagocytic lymphohistiocytosis.

Lgmn was upregulated in lung tissues of PAH mice subjected to hypoxia(HySu) plus SU5416. Deletion of Lgmn systemically inhibits the development of PAH by diminishing ECM protein accumulation in PAs from HySu-treated mice.The synthetic specific Lgmn inhibitor RR-11a protects against PAH. Lgmn promotes ECM protein deposition in PAs involved in activating TGF-beta1.

Study shows that BDNF-mediated Akt directly phosphorylates AEP on T322 and blocks AEP activation, sequestering it in lysosomes. Viral delivery of unphosphorylated T322A mutant into brain of young alpha-SNCA mice accelerates alpha-syn N103 cleavage in alpha-SNCA-Tg mice. Data support the hypothesis that a decrease in BDNF/TrkB signaling in neurodegenerative diseases abolishes p-AEP T322, resulting in AEP upregulation an...

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.
