Recombinant human KIAA0141 protein, also known as SHIP1 (SH2 domain-containing inositol 5-phosphatase 1), is a key regulator of cellular signaling pathways. It was initially identified through genomic sequencing as an open reading frame (KIAA0141) with unknown function. Subsequent studies revealed its role as a lipid phosphatase that hydrolyzes phosphatidylinositol (3.4.5)-trisphosphate [PIP3] to phosphatidylinositol (3.4)-bisphosphate [PI(3.4)P2], thereby modulating PI3K/Akt signaling cascades. This enzyme contains an N-terminal SH2 domain, a central catalytic phosphatase domain, and C-terminal proline-rich motifs, enabling interactions with adaptor proteins and membrane receptors.
KIAA0141/SHIP1 is primarily expressed in hematopoietic cells and participates in immune regulation, apoptosis, and cell proliferation. It acts as a negative regulator of B-cell receptor signaling, cytokine responses, and mast cell activation. Dysregulation of SHIP1 has been implicated in pathologies including leukemia, lymphoma, and autoimmune disorders. Recombinant production of this protein typically involves expression systems like E. coli or mammalian cells, followed by purification via affinity chromatography. The recombinant form enables structural studies, inhibitor screening, and functional assays to investigate its role in cancer biology and immune disorders. Current research focuses on targeting SHIP1 for therapeutic modulation in hematological malignancies and inflammation-related diseases.
