Transformer-2 protein homolog beta, also known as TRA2B previously known as splicing factor, arginine/serine-rich 10 (transformer 2 homolog, Drosophila) (SFRS10), is a protein that in humans is encoded by the TRA2B gene.

TRA2B contains a poison exon whose inclusion is autoregulated by TRA2B protein. Proper regulation of poison exon inclusion in TRA2B is important for T cell fate.

Interactions

TRA2B has been shown to interact with RBMX.
