Summary
Enables several functions, including lipopolysaccharide binding activity; lipoteichoic acid binding activity; and peptidoglycan binding activity. Involved in several processes, including positive regulation of defense response to bacterium; sterol homeostasis; and synaptic target recognition. Located in extracellular space. Is expressed in several structures, including adult heart; embryonic/larval central nervous system; and embryonic/larval digestive system. Human ortholog(s) of this gene implicated in Niemann-Pick disease and Niemann-Pick disease type C2. Orthologous to human NPC2 (NPC intracellular cholesterol transporter 2).

  1. may play a role in the immune deficiency pathway
    Title: Drosophila melanogaster NPC2 proteins bind bacterial cell wall components and may function in immune signal pathways.
  2. Data suggest that npc2a functions redundantly with npc2b in regulating sterol homeostasis and ecdysteroid biosynthesis, probably by controlling the availability of sterol substrate.
