Synthetic peptide corresponding to a region within N-terminal amino acids 51-100 (IPFSFYYPWELATAPDVRISWRRGHFHRQSFYSTRPPSIHKDYVNRLFL N) of Human PILRA isoform 3 (NP_840057). Note: this aminoacid sequence is identical in all 4 isoforms of human PILRA.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 µg/ml. Predicted molecular weight: 34 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
機能Paired receptors consist of highly related activating and inhibitory receptors and are widely involved in the regulation of the immune system. PILRA is thought to act as a cellular signaling inhibitory receptor by recruiting cytoplasmic phosphatases like PTPN6/SHP-1 and PTPN11/SHP-2 via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.
組織特異性Predominantly detected in hemopoietic tissues and is expressed by monocytes, macrophages, and granulocytes, but not by lymphocytes. Also strongly expressed by dendritic cells (DC); preferentially by CD14+/CD1a- DC derived from CD34+ progenitors. Also expressed by CD11c+ blood and tonsil DC, but not by CD11c- DC precursors.
ドメインContains 2 copies of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases. PTPN6 seems to bind predominantly to the first ITIM motif.
