Developmental regulation of gene expression for the MPTPδ isoforms in the central nervous system and the immune system
Copyright policy )Developmental regulation of gene expression for the MPTPδ isoforms in the central nervous system and the immune system
MPTPδ is a murine transmembrane protein tyrosine phosphatase which has three isoforms, types A–C, differing in the structure of the extracellular regions. In this study, we examined MPTPδ isoform expression in the brain and the immune system at discrete developmental or differentiation stages. RT‐PCR analysis demonstrated that another isoform, type D, is transcribed from the MPTPδ gene. In the brain, only type D was expressed until postnatal day 7 (P7), but after P14, all four isoforms were detected. In contrast, the spleen, thymus and all the hematopoietic cell lines examined express only types B and C isoforms. An in situ hybridization study showed that MPTPδ mRNA is diffusely expressed throughout the spleen, but its expression in the thymus is restricted to the medullary region.
