UniProt annotation for BMR1B_HUMAN » Bone morphogenetic protein receptor type-1B
FUNCTION: On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for BMP7/OP-1 and GDF5. Positively regulates chondrocyte differentiation through GDF5 interaction (By similarity).

CATALYTIC ACTIVITY: ATP + [receptor-protein] = ADP + [receptor- protein] phosphate.

SUBUNIT: Interacts with high affinity with GDF5; positively regulates chondrocyte differentiation.

DISEASE: Acromesomelic chondrodysplasia, with genital anomalies (AMDGA) OMIM: A form of chondrodysplasia. Acromesomelic chondrodysplasias are rare hereditary skeletal disorders characterized by short stature, very short limbs and hand/foot malformations. The severity of limb abnormalities increases from proximal to distal with profoundly affected hands and feet showing brachydactyly and/or rudimentary fingers (knob-like fingers). mutations affecting the gene represented in this entry.

DISEASE: Brachydactyly A2 (BDA2) OMIM: A form of brachydactyly. Brachydactyly defines a group of inherited malformations characterized by shortening of the digits due to abnormal development of the phalanges and/or the metacarpals. In brachydactyly type A2 shortening of the middle phalanges is confined to the index finger and the second toe, all other digits being more or less normal. Because of a rhomboid or triangular shape of the affected middle phalanx, the end of the second finger usually deviates radially. mutations affecting the gene represented in this entry.
