A new 5′ terminal murine GAPDH exon identified using 5′RACE LaNe

Abstract

In this work, a ligation-independent, fully gene-specific, nested polymerase chain reaction (PCR) method for the elucidation of 5′ cDNA sequence is described and demonstrated for the first time. Two manifestations of the method, rapid amplification of cDNA ends (RACE) by lariat-dependent nested PCR 5′ (RACE LaNe), at least as simple to perform as conventional RACE, were successfully applied to the murine housekeeping genes phosphoglycerate kinase 1 (PGK1), β-actin (β-ACT), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and the alpha thalassemia mental retardation Y homolog (ATRY) gene of the marsupial, Macropus eugenii. Significantly, a new murine GAPDH 5′ exon, separated by 365 kb of ..
