# Gene transcriptions/Boxes/Ys

The "Y-box [is] an inverted CCAAT box, in the promoter region of many genes; this domain is highly conserved in evolution [1, 3, 4]."

## Human genes

Gene ID: 4904 is YBX1 Y-box binding protein 1. "This gene encodes a highly conserved cold shock domain protein that has broad nucleic acid binding properties. The encoded protein functions as both a DNA and RNA binding protein and has been implicated in numerous cellular processes including regulation of transcription and translation, pre-mRNA splicing, DNA reparation and mRNA packaging. This protein is also a component of messenger ribonucleoprotein (mRNP) complexes and may have a role in microRNA processing. This protein can be secreted through non-classical pathways and functions as an extracellular mitogen. Aberrant expression of the gene is associated with cancer proliferation in numerous tissues. This gene may be a prognostic marker for poor outcome and drug resistance in certain cancers. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on multiple chromosomes."

Gene ID: 51087 is YBX2 Y-box binding protein 2. "This gene encodes a nucleic acid binding protein which is highly expressed in germ cells. The encoded protein binds to a Y-box element in the promoters of certain genes but also binds to mRNA transcribed from these genes. Pseudogenes for this gene are located on chromosome 10 and 15."

## Consensus sequences

On the template strand, the CAAT box consensus sequence is 3'-(C/T)(A/G)(A/G)CCAATC(A/G)-5'. An inverted CAAT box has the consensus sequence 3'-(A/G)CTAACC(A/G)(A/G)(C/T)-5'.
