Technical Data
ATXN2L, Isoform B (Ataxin-2-like Protein, Ataxin-2 Domain Protein, Ataxin-2-related Protein, A2D, A2LG, A2LP, A2RP)
Ataxin 2 related protein isoform B is a component of a cytokine signaling cascade, having three regions similar to those of Ataxin-2, with the gene product causing familial type 2 spinocerebellar ataxia. The protein has several isoforms with different C-terminal domains, all produced from a single gene by alternative splicing. Northern blotting indicated that the gene is widely expressed in immortalized cell lines and hematopoietic and fetal tissues. The gene encoding for human Ataxin 2 related protein isoform B is localized on human chromosome 16p11. The protein is constitutively associated with cytokine receptor Mpl in vivo in human hematopoietic UT7 cells. The protein binds to the unstimulated erythropoietin receptor, whereas erythropoietin caused dissociation from the erythropoietin receptor, suggesting that the protein is a new component of the cytokine signaling system. The synthesis of the protein is greatly increased during megakaryocytic differentiation.
