TCEAL5 (Transcription Elongation Factor A Like 5), which is located on the X chromosome, encodes a protein which contains a BEX (brain expressed X-liked like family) domain. This domain is found in proteins encoded by the TCEAL elongation factor (transcription elongation factor A (SII)-like) gene family also located on the X chromosome. The coding region for TCEAL5 is located entirely in the terminal exon.
