TUC338 (transcribed ultra-conserved region 338) is an ultra-conserved element which is transcribed to give a non-coding RNA.[1][2] The TUC338 gene was first identified as uc.338, along with 480 other ultra-conserved elements in the human genome.[3] Expression of this RNA gene has been found to dramatically increase in hepatocellular carcinoma (HCC) cells.[4]

The TUC338 RNA gene is 590 base-pairs long, and partially overlaps the gene encoding Poly(rC)-binding protein 2 (PCBP2), a protein involved in mRNA processing.[5] Despite this overlap, PCBP2 and TUC388 were found to be independently expressed.[4]

TUC338 is predicted to function in cell growth, possibly at the interface between G1 phase and S phase, and could potentially present a therapeutic target to treat HCC cells.[4] Experimental evidence shows knocking out TUC338 using siRNA reduced the growth rate of both mouse and human HCC cells.[4]
