Activity summary

The Bcr protein also known as breakpoint cluster region protein plays an important role in cellular signaling. It has a molecular mass of approximately 160 kDa and is expressed in many cell types such as hematopoietic cells. Bcr functions as a GTPase-activating protein (GAP) for p21rac and other small GTP-binding proteins. This activity influences cellular processes such as growth and differentiation. Bcr is also known for its involvement in the formation of the Bcr-Abl fusion protein an important factor in certain leukemias.

Biological function summary

The Bcr protein acts within cells to regulate signal transduction and cytoskeletal organization. It is part of the pre-B cell receptor (pre-BCR) signaling complex influencing B-cell development. Its GAP activity is important for the regulation of small GTPases impacting cell migration and adhesion. Alterations in Bcr function can affect cellular responses such as apoptosis making it a focus for research into targeted therapies for hematological conditions.

Pathways

The Bcr protein is an important player in signaling pathways involving the Ras superfamily of small GTPases. It is notably involved in the Rho GTPase pathway tied to cytoskeletal dynamics and cell cycle progression. Bcr's interaction with these pathways puts it in relation to proteins like Rac and Cdc42 which are vital for various cellular processes. Disruption in Bcr-associated pathways can lead to aberrant cell growth and metastasis.

Associated diseases and disorders

Bcr has a well-documented link to certain leukemias particularly chronic myeloid leukemia (CML). The Bcr-Abl fusion protein resulting from the translocation of chromosomes 9 and 22 is central to CML pathology. Additionally Bcr connects with other proteins such as Abl in this disease context. Further disruptions in Bcr signaling can relate to disorders involving immune system dysregulation demonstrating the protein's relevance in both oncology and immunology research.
