Orchestrated Egr1 and Pitx1 activities depending on specific central and peripheral regulatory inputs could be responsible for physiologically variable Lhb gene promoter activation in vivo.

GnRH stimulates AMPK, and AMPK inhibition suppresses GnRH-stimulated LHbeta transcription.
Title: AMP-activated protein kinase is a key intermediary in GnRH-stimulated LHβ gene transcription.
data suggest that the molecular decision for LHbeta subunit to enter the regulated secretory pathway is a pre-Golgi event controlled by the C-terminal heptapeptide.
Title: A novel carboxyl-terminal heptapeptide initiates the regulated secretion of LH from unique sub-domains of the ER.
increased LH concentration induces production of incomplete LHR transcripts in hippocampal cells and decreases immature LHR at the protein level
Title: Regulation of luteinizing hormone receptor in hippocampal neurons following different long-lasting treatments of castrated adult rats.
Data suggest that LH beta subunit expression (and FSH beta subunit expression) is regulated by DUSP1 expression (specifically in response to high-frequency GnRH pulses); this effect may occur in association with MAPK3/1 phosphorylation.

LHbeta promoter activity is further regulated by the orphan nuclear receptors, chicken ovalbumin upstream promoter-transcription factors (COUP-TFI and COUP-TFII).
Title: The orphan nuclear receptors COUP-TFI and COUP-TFII regulate expression of the gonadotropin LHβ gene.
data suggest that LHbeta G1502A polymorphism may be involved in the predisposition to infertility and minimal/mild endometriosis-associated infertility, although endometriosis might be only a coincidental finding along with infertility.
Title: Luteinizing hormone beta-subunit gene (LHbeta) polymorphism in infertility and endometriosis-associated infertility.
Exaggerated release of gonadotropins in rats primed with GnRH antagonist and treated with GnRH agonist was due to an increase in releasable gonadotropin pools coupled with a reduction in GnRH-R, but receptor function was preserved.
Title: The mechanism responsible for the supraphysiologic gonadotropin surge in females treated with gonadotropin-releasing hormone (GnRH) agonist and primed with GnRH antagonist.
These results suggest that the expression of LHbeta in the ovary is regulated by locally produced GnRH and by FSH from either the ovary or the pituitary.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
