Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR101-1 is a microRNA precursor that has been observed to significantly decrease in expression in certain brain regions when comparing long-term and acute responses to ischemic brain injury with immediate brain artery occlusion [PMC7848201]. This miRNA is also a part of the top-ranked miRNA expression signatures, indicating its potential role in the molecular response to ischemic events [PMC9284388]. In relation to immune response, MIR101-1 expression has been correlated with Th2 cell-related genes and is implicated in the regulation of immune cell function [PMC9380889]. Interestingly, MIR101-1 has a target sequence that can be extended by certain genetic variants, suggesting that genetic differences may influence its regulatory potential [PMC3198095]. Despite its regulatory capabilities, MIR101-1 does not target SUV39H2 mRNA according to predictions from TargetScan [PMC3198095]. In comparative studies of miRNA paralogues, MIR101-1 is distinguished from its paralogue MIR101-2 by uniquely aligned read pairs in small RNA-seq datasets, which emphasizes its unique presence and function [PMC6901076]. Moreover, MIR101-1 has been found notably down-regulated in patients with Parkinson's disease (PD), which may suggest a role for this miRNA in neurodegenerative processes [PMC5288660].

Comments
Reference [1] reports two miR-101 precursor hairpin structures in human, on chromosome 1 (MIR:MI0000103) and 9 (MIR:MI0000739, named mir-101-precursor-9 in [1]). The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [3].
