Annotation (From lncRNAdb)

[NONHSAT119717]

Section	Description
ID	HOTTIP
Characteristics	Gene located at 5°Ø end of HoxA cluster, bidirectional transcript with HOXA13 (Sasaki (2007)). ~3.8kb, transcript in human, spliced and polyadenylated (Wang (2011)). ~2.3kb transcript in mouse, different splice isoforms, currently known transcripts initiate downstream from the syntenic site in human.
Expression	Shows collinear regulation of expression like HOX protein coding genes (Sasaki (2007)). Has bivalent chromatin marks (both H3 K4me3 and H3 K27me3) whether expression off or on, but only expressed in more distal cells (Wang (2011)). Has a similar expression profile to HOXA13, expressed in colon, prostate, placenta and uterus, as well as hand, foreskin and foot fibroblasts (Sasaki (2007), Sasaki (2007), Wang (2011)). Mouse E13.5 in-situs gave similar results (Wang (2011)). Nuclear localised, generally to a single small nuclear spot (Wang (2011)). Lowly expressed, estimated at ~0.3 copies/cell in expressing tissues (Wang (2011)).
Function	Summary:. Controls activation of 5°Ø HOXA genes. Chromosomal lopping bring it into close association with 5°Ø gene loci. HOTTIP binds WDR5 and recruits a MLL chromatin modifiying complex to maintain a domain of active chromatin over the 5°Ø of HOXA cluster (Wang (2011)). - HOTTIP controls activation of 5°Ø HOXA genes in mammals and chicken. - Impact on HOXA genes decreases with increased genomic distance from HOTTIP. - Phenotypic impact in chicken forelimb of HOTTIP knockdown was shorter than normal distal bones. - HOTTIP doesn°Øt affect chromosomal structure and looping but it was necessary for maintenance of H3 K4me3 chromatin marks over the distally expressed 5°Ø half of the HOXA locus. HOTTIP RNA binds WDR5 a component of MLL/Trithorax complexes recruiting a MLL complex to lay down H3 K4me3 marks. - WDR5 binding mediated by sequence(s) in 5°Ø 1kb of HOTTIP. HOTTIP appears to act in cis, its function is facilitated by the chromosomal looping that brings it into close proximity with 5°Ø HOXA genes.
Conservation	Present in human and mouse. Portions of HOXA13as sequence are well conserved throughout mammals (Wang (2011)). Appears to be present in chicken although there is little homology (Wang (2011)). RNA contains some highly conserved sequences which are predicted to form a conserved structure (Sasaki (2007)).
Misc	Background: Hox genes are found in 4 clusters. Genes in each cluster are expressed in certain tissues along body axes dependent on their position in the cluster. In the HoxA cluster genes near the 5°Ø are expressed in more distal tissues while genes near the 3°Ø are expressed in more proximal tissues. Expressed genes have active chromatin marks and show close physical association (likely due to chromosomal looping). Inactive genes do not associate and have repressive chromatin marks (Wang (2011)). Human clone accession: GU724873. Mouse clone accession: BC046496
Name	HOTTIP - HOXA transcript at the distal tip
