B0336.7 encodes, by alternative splicing, two isoforms of a protein witha THAP or THAP-like domain; other proteins with such domains includeLIN-15A, LIN-15B, LIN-36, and HIM-17 (which all interact withLIN-35/Rb), as well as CDC-14B, CTB-1, GON-14, and ~100 other proteinssuch as Drosophila P element transposase and human nuclear proapoptoticfactor THAP1; B0336.7 is expressed in intestine and amphid neurons.
