TBC1D20 Is Essential for Mouse Blood-Testis Barrier Integrity Through Maintaining the Epithelial Phenotype and Modulating the Maturation of Sertoli Cells.
Title: TBC1D20 Is Essential for Mouse Blood-Testis Barrier Integrity Through Maintaining the Epithelial Phenotype and Modulating the Maturation of Sertoli Cells.
It suggested that TBC1D20 deficiency triggers irreversible endoplasmic reticulum stress resulting in G1/S arrest and excessive apoptosis in TBC1D20-deficient Sertoli cells, and TBC1D20 deficiency in Sertoli cells may also contribute to the infertility phenotype in 'blind sterile' male mice.

TBC1D20 has an essential role in the maturation of autophagosomes.
Title: TBC1D20 mediates autophagy as a key regulator of autophagosome maturation.
Disruption of Tbc1d20 in mice results in cataracts and aberrant acrosomal formation.

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.
