In molecular biology, JPX transcript, XIST activator (non-protein coding), also known as Jpx, is a long non-coding RNA. In humans, it is located on the
X chromosome. It was identified during
sequence analysis of the
X inactivation centre, surrounding the
Xist gene.[3] Jpx upregulates expression of Xist.[4]
