title: Localization of the human A1S9 gene complementing the ts A1S9 mouse L-cell defect in DNA replication and cell cycle progression to Xp11.2----p11.4.
abstract: The temperature-sensitive ts A1S9 mouse L-cell mutant is defective in an X-linked gene essential for progression of cells through the S phase of the cell division cycle. A single copy fragment derived from the complementing human A1S9 gene was used as a probe to localize the gene on the X chromosome. Southern blot analysis of human x rodent hybrids and in situ hybridization to human metaphase chromosomes allowed the regional assignment of the human A1S9 gene to Xp11.2----p11.4.
