About: HOTTIP

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In molecular biology, HOTTIP (HOXA transcript at the distal tip) is a long non-coding RNA. The gene encoding HOTTIP is located at the 5′ tip of the HOXA locus, and coordinates the activation of several of the 5′ HOXA genes. The non-coding RNA is brought into close proximity with the HOXA genes by chromosomal looping. HOTTIP binds to the WDR5 protein, which forms a complex with the histone methyltransferase protein MLL. This targets the WDR5-MLL complex to the HOXA region and results in H3K4 methylation and transcriptional activation of the HOXA locus.More recently, HOTTIP has been shown to play a role in Hepatocellular Carcinoma (HCC) progression. HOTTIP expression levels predict metastasis formation and poor disease outcome in HCC patients. HOTTIP has been shown to be transcriptionally re

  • In molecular biology, HOTTIP (HOXA transcript at the distal tip) is a long non-coding RNA. The gene encoding HOTTIP is located at the 5′ tip of the HOXA locus, and coordinates the activation of several of the 5′ HOXA genes. The non-coding RNA is brought into close proximity with the HOXA genes by chromosomal looping. HOTTIP binds to the WDR5 protein, which forms a complex with the histone methyltransferase protein MLL. This targets the WDR5-MLL complex to the HOXA region and results in H3K4 methylation and transcriptional activation of the HOXA locus.More recently, HOTTIP has been shown to play a role in Hepatocellular Carcinoma (HCC) progression. HOTTIP expression levels predict metastasis formation and poor disease outcome in HCC patients. HOTTIP has been shown to be transcriptionally regulated by a transcriptional coactivator PSIP1/p52 (en)
