KIR3DP1 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells andsubsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies amonghaplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4,KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and bywhether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduceinhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins withthe short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase bindingprotein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules;thus, KIR proteins are thought to play an important role in regulation of the immune response. This gene is one of the"framework" loci that is present on all haplotypes. This gene is considered to be a pseudogene based on theabsence of transcription and it lacks several functional domains compared to other killer cell immunoglobulin-likereceptors.
