Helicase-like transcription factor is an enzyme that in humans is encoded by the HLTF gene.^[5]^[6]

Function

This gene encodes a member of the SWI/SNF family. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein contains a RING finger DNA binding motif. Two transcript variants encoding the same protein have been found for this gene. However, use of an alternative translation start site produces an isoform that is truncated at the N-terminus compared to the full-length protein.^[6]

HLTF is a double-stranded DNA translocase, one of two human homologs of Saccharomyces cerevisiae RAD5 besides SHPRH (SNF2 histone linker PHD RING helicase), that is able to carry out fork regression, similarly to Rad5.^[7]

Interactions

HLTF has been shown to interact with UBE2N,^[8] RAD18 ^[8] and UBE2V2 ^[8](see also STRING functional and physical associations network : under the option 'search by name' enter 'protein name' of interest, HLTF, klick on 'GO! ', choose 'organism ', klick on 'continue ->' ).

Nuclear respiratory factor 1, also known as Nrf1, Nrf-1, NRF1 and NRF-1, encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication. The protein has also been associated with the regulation of neurite outgrowth. Alternate transcriptional splice variants, which encode the same protein, have been characterized. Additional variants encoding different protein isoforms have been described but they have not been fully characterized. Confusion has occurred in bibliographic databases due to the shared symbol of NRF1 for this gene and for "nuclear factor -like 1" which has an official symbol of NFE2L1.
