What is the official name of the HS1BP3 gene?

The official name of this gene is “HCLS1 binding protein 3.”

HS1BP3 is the gene's official symbol. The HS1BP3 gene is also known by other names, listed below.

What is the normal function of the HS1BP3 gene?

The HS1BP3 gene provides instructions for making a protein called hematopoietic-specific protein 1 binding protein 3. This protein is believed to help regulate chemical signaling in the brain region involved in coordinating movements (the cerebellum) and in specialized nerve cells in the brain and spinal cord that control the muscles (motor neurons).

Where is the HS1BP3 gene located?

Cytogenetic Location: 2p24.1

Molecular Location on chromosome 2: base pairs 20,617,803 to 20,651,103

The HS1BP3 gene is located on the short (p) arm of chromosome 2 at position 24.1.

The HS1BP3 gene is located on the short (p) arm of chromosome 2 at position 24.1.

More precisely, the HS1BP3 gene is located from base pair 20,617,803 to base pair 20,651,103 on chromosome 2.
