"Deletion, mutagenesis, and tandem repeat analyses identified the core responsive element as the region between −89 and −60 bp (termed the hypertrophy box [HY box]), which showed specific binding to RUNX‐2."[1]

The "HY box is the core element responsive to RUNX‐2 in human COL10A1 promoter."[1]

Boxes

A repeating sequence of nucleotides that forms a transcription or a regulatory signal is a box.

Consensus sequences

"Deletion analysis by a series of 5′-deletion constructs identified the responsive region to RUNX-2 as being between −81 bp and −76 bp, containing a putative RUNX-2 binding sequence (TGAGGG), which is similar to that identified in the promoter region of human interleukin-3 (TGTGGG) (33)."[1] This suggests a consensus sequence of 3'-TG(A/T)GGG-5' on the template strand in the direction of transcription.

RUNX2

The gene RUNX2 "is a member of the RUNX family of transcription factors and encodes a nuclear protein with an Runt DNA-binding domain. This protein is essential for osteoblastic differentiation and skeletal morphogenesis and acts as a scaffold for nucleic acids and regulatory factors involved in skeletal gene expression. The protein can bind DNA both as a monomer or, with more affinity, as a subunit of a heterodimeric complex."[2]

COL10A1

The gene COL10A1 "encodes the alpha chain of type X collagen, a short chain collagen expressed by hypertrophic chondrocytes during endochondral ossification. Unlike type VIII collagen, the other short chain collagen, type X collagen is a homotrimer."[3]

Human COL10A1, GeneID: 1300, has an HY box as the core responsive element.[1]

Hypotheses

  1. A1BG is not transcribed by an HY box.

HY box samplings

For the Basic programs (starting with SuccessablesHY.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
