摘要:
Mammal transcription factor APRF, process for the preparation of it, DNAs encoding the said product, replication and expression vector comprising the said DNA, host cells transformed or tranfected with the said replication and expression vector, evaluating and screening method for searching an inhibitory agent on the function of APRF and an inhibitory agent against the function of the said APRF. The peptide of the present invention (APRF) may be useful for complement or suppression of the function of APRF, screening an inhibitory agent against the function of APRF. Inhibiting agent containing the said product as active ingredient of the present invention may be also useful for treatment of diseases related cytokine such as IL-6 i.e. inflammatory diseases.
摘要:
Human gp130 protein having at least the following properties: (1) the protein has an affinity with a complex of IL-6 (interleukin-6) and an IL-6 receptor (interleukin-6 receptor); (2) the protein shows an apparent molecular weight of 130 kDa in SDS-polyacrylamide electrophoresis; and (3) the protein participates in the transmission of IL-6 signal; DNA coding for the protein, an expression plasmid containing the DNA; and a process for production of the protein using the expression plasmid.
摘要:
Isolated receptor proteins for human B cell stimulating factor-2 are capable of specifically binding to human B cell stimulating factor-2. DNA coding for the above-mentioned receptor protein, expression vectors containing the above-mentioned DNA, host organisms transformed with the above-mentioned expression vector, a process for production of the receptor protein comprising culturing the host organisms in a medium to produce the receptor protein and recovering the receptor protein from the culture, and an antibody reacting with the protein are also disclosed.
