Description

The abstract shows MTNR1A displays diurnal rhythm but hnRNPL does not, yet hnRNPL binding to MTNR1A is enhanced at midnight when MTNR1A peaks. The molecular basis for this selective rhythmicity despite their functional interaction remains unexplained.

Gap type: unexplained_observation Source paper: The MTNR1A mRNA is stabilized by the cytoplasmic hnRNPL in renal tubular cells. (2021, Journal of cellular physiology, PMID:32730662)
