Genomic structure and chromosomal localization of TCEAL1, a human gene encoding the nuclear phosphoprotein p21/SIIR.
[No authors listed]
摘要
Human p21/SIIR is a novel Ser/Arg/Pro-rich nuclear phosphoprotein that is 48% similar to transcription factor SII and modulates transcription in a promoter context-dependent fashion. We have obtained the complete sequence of TCEAL1, the gene that codes for p21/SIIR. This gene consists of three exons and two introns with the entire coding sequence in exon III. Tissue-specific expression patterns of TCEAL1 by Northern blot analysis showed the presence of an approximately 1.2-kb transcript in all normal human tissues examined, and heart and skeletal muscle contained an additional transcript of approximately 7 kb. Expression was lowest in hematopoietic cells of both normal and tumor origin. TCEAL1 was mapped to human chromosome Xq22.1 by fluorescence in situ hybridization.
