  1. Current study shows that high SNTB2 in obese adipose tissues restricts adipocyte growth and thereby may contribute to metabolic diseases.

  2. Suggest alpha/beta2-syntrophins do not regulate ABCA1 activity and insulin release but may have a role in regulating glucose uptake, ERK and SR-BI levels, and sphingomyelin metabolism in obesity.

  3. ICA512-CCF also dimerizes with intact ICA512 on granules, thereby displacing it from beta2-syntrophin.

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.
