Core component of the DBIRD complex, a multiprotein complex that acts at the interface between core mRNP particles and RNA polymerase II (RNAPII) and integrates transcript elongation with the regulation of alternative splicing: the DBIRD complex affects local transcript elongation rates and alternative splicing of a large set of exons embedded in (A + T)-rich DNA regions (By similarity). May also play a role in neuronal differentiation. Able to bind DNA and activate expression in vitro. Component of the DBIRD complex. Interacts with CCAR2; the interaction is direct (By similarity). Ubiquitously expressed in adult tissues. Highly expressed in neuronal tissues such as brain and neural tube. Weakly expressed during 9.5 dpc and 10.5 dpc, expressed at highest level in 11.5 dpc and gradually decreases thereafter. During the cell cycle, it is weakly expressed in G0 and G1 phases. It increases during G1, S, G2 and M phases. Upon retinoic acid treatment. Belongs to the AKAP95 family. Contaminating sequence. Potential poly-A sequence.
