The BMPR1B receptor plays a role in the formation of middle and proximal phalanges [1] In the chick embryo, it has been shown that BMPR1B is found in precartilaginous condensations.[2] BMPR1B is the major transducer of signals in these condensations as demonstrated in experiments using constitutively active BMPR1B receptors[2]. BMPR1B is a more effective trasducer of GDF5 than BMPR1A[2]. Unlike BMPR1A null mice, which die at an early embryonic stage, BMPR1B null mice are viable[2].
