There are a number of ELISA Kits available for the measurement of Interleukin-1 Receptor-associated kinase 1, another term for the human protein, interleukin 1 receptor associated kinase 1. Other synonyms may include: IRAK-1, Pelle homolog, IRAK, and pelle. It is encoded by the IRAK1 gene to yield a protein 712 amino acids in length and 76.5 kDa in size. However, there are up to 4 reported isoforms. The protein, an enzyme, is categorized into the Protein kinase superfamily, TKL Ser/Thr protein kinase family, Pelle subfamily. Versions of Interleukin-1 Receptor-associated kinase 1 are present in other organisms, including: Mouse, Rat, Zebrafish.
