Proteins that specifically bind to RNA CAPS and form nuclear cap binding protein complexes. In addition to stabilizing the 5' end of mRNAs, they serve a diverse array of functions such as enhancing mRNA transport out of the CELL NUCLEUS and regulating MRNA TRANSLATION in the CYTOPLASM.

A heterodimeric protein complex of RNA cap-binding proteins which binds with high affinity to the 5' MRNA CAP STRUCTURE.
