A core responsive element is the hypertrophy region HY box between -89 and -60 nucleotides (nts) upstream from the transcription start site.[1]

BoxesEdit

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

Consensus sequencesEdit

"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.

RUNX2Edit

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]

COL10A1Edit

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]

HypothesesEdit

  1. A1BG is not transcribed by an HY box.
