'''Purine-rich element binding protein alpha''' (Purα or PurA)~~, encoded by the PURA gene~~ is a transcription factor with a molecular weight of ~35 kDa. It is known to recognize and bind sequence specific purine-rich regions of ssDNA and ssRNA. Purα is a member of the PUR family of proteins, which includes cousins Purβ and two isoforms of Purγ. In its functional dimeric form Purα is known to repress expression of genes encoding smooth muscle alpha actin (SMαA) and ____. It also plays a crucial role in nervous system development and is known to be involved in cell cycle regulation. Mutations in Purα have been implicated in two neurological diseases: Purα Syndrome and Fragile X-associated Tremor/Ataxia Syndrome (FXTAS) (see Disease section).
