Anti-PIWIL1 (Piwi-like Protein 1, HIWI)

HIWI, also called PIWIL1 is an 861aa, 99kD (predicted) cytoplasmic protein of the PIWI subgroup of the Argonaute family. PIWI domains bind a class of ~29-30 nucleotide RNAs termed piRNAs. PIWIL1 orthologs are expressed with piRNAs in germ cells and are essential for spermatogenesis in mice. CD34+ hematopoietic progenitor cell PIWIL1 is downregulated upon differentiation. When overexpressed in leukemic cell lines, PIWIL1 inhibits growth and induces apoptosis. Human PIWIL1 shares 95% aa sequence identity with mouse and rat PIWIL1.
