The gene is a member of the
inositol-polyphosphate 5-phosphatase family. The encoded protein interacts with the
ras-related C3 botulinum toxin substrate 1, which causes translocation of the encoded protein to the
plasma membrane where it inhibits
clathrin-mediated
endocytosis. Alternative splicing results in multiple
transcript variants. [provided by RefSeq, May 2010]. == References ==
