"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

Main articles: Box gene transcriptions and Boxes

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

Consensus sequences

Main article: 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

Main article: Hypotheses
  1. A1BG is not transcribed by an HY box.

Comparison:

The occurrences of real responsive element consensus sequences are larger than the randoms. This suggests that the real responsive element consensus sequences are likely active or activable.
