What's a GeneRIF?

Weight-dependent quantitative variation in Tnnt3 alternative splicing appears to be an evolutionarily conserved feature of skeletal muscle.
Title: Body weight-dependent troponin T alternative splicing is evolutionarily conserved from insects to mammals and is partially impaired in skeletal muscle of obese rats.
HU induced profound slow-to-fast isoform transitions of all Tn subunits, although to different extents and with different time courses. This suggests that slow and fast counterparts of Tn subunit isoforms are regulated independently in response to HU.
Title: Time-dependent changes in expression of troponin subunit isoforms in unloaded rat soleus muscle.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
