What is "hnrpab"

Heterogeneous nuclear ribonucleoprotein A/B, also known as HNRPAB, is a protein which in humans is encoded by the HNRPAB gene. Although this gene is named HNRNPAB in reference to its first cloning as an RNA binding protein with similarity to HNRNP A and HNRNP B, it is not a member of the HNRNP A/B subfamily of HNRNPs, but groups together closely with HNRNPD/AUF1 and HNRNPDL.
