Contents
Evolution
MINPP1 is found broadly in eukaryotes but absent from many genomes, such as C elegans. Human has a single copy, but yeast have as many as five copies.
Domain
MINPP1 has phosphatase domain and N-terminal signal peptide cleavage site.
Functions
Human MINPP1 is the only hitherto known InsP6 phosphatase. It has been shown to be predominantly localized in the lumen of the ER (endoplasmatic reticulum) [1, 2].
