Background: SIRP delta

SIRPD (Signal Regulatory Protein Delta), also know as Protein Tyrosine Phosphatase non-Receptor Type Substrate 1-l Like 2 (PTPNS1L2), is member of the signal regulatory proteins (SIRPS) family (1). SIRPD contains a 168 amino acid Ig-like domain that is characteristic of other SIRP family members (1). Unlike other members of SIRPS family, SIRPD lacks the transmemberane region, and is secreted (2). Murine homologs of SIRPD are not characterized. Expression sequence tag analysis suggests that SIRPD may be expressed in sperm cells and respiratory tissue (2). Using BioPlex 2.0 (Biophysical Interactions of ORFeome-derived complexes) high-throughput affinity purification–mass spectrometry (AP–MS) analysis to identify probable protein–protein interactions, several candidate SIRPD interactions were found including DIRAS2 (3). In-house testing indicates SIRPD can interact with DIRAS2.
