Abstract
Mutations in the X-linked gene doublecortex (DCX) result in lissencephaly in males or subcortical laminar heterotopia (double cortex) in females. Recently, an evolutionarily conserved doublecortin (DC) domain important for microtubule binding and microtubule polymerization was defined according to detailed sequence analysis of DCX and DCX-like proteins. Subsequently we cloned a novel human cDNA that contained a DC domain during large-scale DNA sequencing of the human fetal brain cDNA library, and termed it doublecortin-domain-containing 1 (DCDC1). According to a search against the human genome database, DCDC1 was mapped to 11p13. Expression analysis showed that DCDC1 was mainly expressed in adult testis. Furthermore, the expression level of DCDC1 in fetal brain was much higher than in adult brain.
