Chromosomal reallocation of the chicken c‐myb locus and organization of 3′‐proximal coding exons

Abstract
In the course of our studies concerning the tissue‐specific expression of the c‐myb proto‐oncogene, we have established the nucleotide sequence of the chicken c‐myb 3′‐proximal coding exons. In situ hybridization performed with different genomic DNA probes corresponding to nearly all the c‐myb gene allowed us to localize the corresponding locus on the large acrocentric chromosome 3 in chicken. Our sequencing data also indicate that the 3′‐proximal noncoding sequences represented in c‐myb mRNA species are derived from non‐contiguous exons.
