Characteristics
XACT is a 251.8-kb transcription unit(112,983,323–113,235,148 bp) and it locates on chromosome Xq23 between the protein-coding genes AMOT and HTR2C [1]. XACT is in an intergenic domain of 1.7 Mb [1].
Cellular Location
XACT is mostly in the nucleus [1].
Function
XACT has a role in the control of human XCI (X-chromosome inactivation) initiation [1].
(a)Localization of XACT and XIST on the human X chromosome (b)RT-PCR analysis (c,d,e)FISH analysis (f) Three-dimensional model of the nuclear volumes occupied by XACT and XIST RNAs.[1]
Evolution
XACT is not conserved in mouse [1].
Expression
XACT is expressed in both X chromosomes in humans but not in mice, and the expression of XACT is restricted to pluripotent cells [1].
Disease
chromosome inactivation
