Purity ~90% (SDS-PAGE). TCEAL1 (Transcription elongation factor A protein-like 1) is belongs to transcription elongation factor A (SII)-like (TCEAL) family. This family may function as nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. It involved in transcriptional regulation. This protein expressed in all tissues, especially highly expressed in heart, ovary, prostate and skeletal muscle. Source: Recombinant corresponding to aa1-159 of human TCEAL1, fused with His-tag at C-terminus, expressed in E.coli.
