PG - 215-21 AB - Murine Sipa-1 (signal-induced proliferation associated protein) is a mitogen induced GTPase activating protein (GAP). While mapping candidate genes for multiple endocrine neoplasia type 1 (MEN1) at 11q13, we cloned the human homologue of Sipa-1. Herein, we report the complete cDNA sequence, expression, and genomic organization of SIPA-1. SIPA-1 consists of 16 exons with highly conserved exon-intron boundaries. The predicted SIPA-1 protein is highly homologous to the mouse protein, particularly in the region of the GAP-related domain at the amino terminus and the leucine zipper at the carboxy terminus. It is widely expressed, including in fetal tissues, but is most highly expressed in lymphoid organs. During the course of cloning SIPA-1, the MEN1 gene was identified, thus excluding human SIPA-1 as a candidate for this disease.
