A number of ELISA Kits are available that target BR1b, an alias of the protein, bone morphogenetic protein receptor type 1B. The human protein, encoded by the gene BMPR1B, is an enzyme and member of the Protein kinase superfamily, TKL Ser/Thr protein kinase family, TGFB receptor subfamily. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: ALK-6, ALK6, AMDD, BDA1D, BDA2, CDw293. Homology is conserved in other species, such as Mouse, Rat, Frog.
