Small heterodimer partner
| View/Edit Human | View/Edit Mouse |
The small heterodimer partner (SHP) also known as NR0B2 (nuclear receptor subfamily 0, group B, member 2) is a protein that in humans is encoded by the NR0B2 gene.[3] SHP is a member of the nuclear receptor family of intracellular transcription factors.[4] SHP is unusual for a nuclear receptor in that it lacks a DNA binding domain. Therefore, technically it is neither a transcription factor nor nuclear receptor but nevertheless it is still classified as such due to relatively high sequence homology with other nuclear receptor family members.
Function
The principal role of SHP appears to be repression of other nuclear receptors through association to produce a non-productive heterodimer.[5] The protein has been shown to interact with retinoid and thyroid hormone receptors, inhibiting their ligand-dependent transcriptional activation. In addition, interaction with estrogen receptors has been demonstrated, leading to inhibition of function. Studies suggest that the protein represses nuclear hormone receptor-mediated transactivation via two separate steps: competition with coactivators and the direct effects of its transcriptional repressor function.[3]
