CC -!- FUNCTION: 5'->3' DNA exonuclease which digests single-stranded DNA
CC (ssDNA) (By similarity). Regulates inflammatory cytokine responses via
CC the degradation of nucleic acids, by reducing the concentration of
CC ssDNA able to stimulate TLR9, a nucleotide-sensing receptor in
CC collaboration with PLD4 (By similarity). May be important in myotube
CC formation. Plays a role in lysosomal homeostasis. Involved in the
CC regulation of endosomal protein sorting (By similarity).
CC {ECO:0000250|UniProtKB:O35405, ECO:0000250|UniProtKB:Q8IV08}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exonucleolytic cleavage in the 5'- to 3'-direction to yield
CC nucleoside 3'-phosphates.; EC=3.1.16.1;
CC Evidence={ECO:0000250|UniProtKB:Q8IV08};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q8IV08}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8IV08}. Lysosome lumen
CC {ECO:0000250|UniProtKB:Q8IV08}. Early endosome membrane
CC {ECO:0000250|UniProtKB:Q8IV08}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8IV08}. Late endosome membrane
CC {ECO:0000250|UniProtKB:Q8IV08}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8IV08}. Golgi apparatus membrane
CC {ECO:0000250|UniProtKB:Q8IV08}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8IV08}. Endosome membrane
CC {ECO:0000250|UniProtKB:Q8IV08}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8IV08}. Note=Localizes to ER-associated
CC vesicles in differentiating myotubes. The soluble form in lysosome
CC arises by proteolytic processing of the membrane-bound form.
CC {ECO:0000250|UniProtKB:Q8IV08}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:Q8IV08}.
CC -!- PTM: Proteolytically processed to a soluble form that is stable within
CC endosomes and lysosomes. During transport through the secretory pathway
CC becomes proteolysed by cysteine proteases, thereby releasing a stable
CC soluble lysosomal lumenal polypeptide, whereas the transmembrane-bound
CC fragment is rapidly degraded. Its transport route to lysosomes involves
CC ubiquitination and the ESCRT complex. {ECO:0000250|UniProtKB:Q8IV08}.
CC -!- PTM: Ubiquitinated. Ubiquitination mediates sorting into lysosomes.
CC {ECO:0000250|UniProtKB:Q8IV08}.
CC -!- SIMILARITY: Belongs to the phospholipase D family. {ECO:0000305}.
CC -!- CAUTION: It was initially thought that PDL3 has phospholipase D
CC activity due to its HKD motifs. The second HKD motif contains Glu
CC instead of the canonical Asp. Its enzyme activity is therefore unsure.
CC Catalytic phospholipase D activity is still controversial (By
CC similarity). Its closest homolog PLD4, exhibits no phospholipase
CC activity (By similarity). {ECO:0000250|UniProtKB:O35405,
CC ECO:0000250|UniProtKB:Q8BG07}.
