title: Sequence analysis of 5'-flanking region of human pax-5 gene exon 1B.
abstract: Pax-5 gene is important transcription factor in B-lymphopoiesis and B-cell development. To understand the regulatory mechanism of pax-5 expression, the immediate 5'-flanking region (6 671 bp) of human pax-gene exon 1B was isolated and characterized. Analysis of the total sequence showed that the proximal promoter includes 3 CAT boxes, 1 SP1 and 1 E box. However, there was no consensus sequence for a TATA box in the 5'-flanking region. Putative regulatory sites of further upstream in the sequence revealed 6 LMO(2)COM, 5 NFAT, 2 LPOLYA-B, 3 GATA1, 2 AP4, 10 MZF1, 1 ETS1-B, 1 GATA3, 1 NKX25, 2 RORA1, 1 LYF1, 2 Ikaros2, 2 TCF11, 1 GATA-C and 1 FREAC7. Therefore, the 5'-flanking region of human pax-5 exon 1B could be involved in regulating the expression of human pax-5 and B-cell differentiation and development.
