Knockout of SLy1 decreases double-negative thymocyte proliferation and protects mice from p53-induced tumor formation.

SASH3 variants cause a novel form of X-linked combined immunodeficiency with immune dysregulation.
Title: SASH3 variants cause a novel form of X-linked combined immunodeficiency with immune dysregulation.
In this report, the structure of the SLy1 SAM domain was solved and revealed that this SAM domain forms a symmetric homodimer through a novel interface. The interface consists primarily of the two long C-terminal helices, alpha5 and alpha5', of the domains packing against each other.
Title: Structure of the SLy1 SAM homodimer reveals a new interface for SAM domain self-association.
We also carried out transgene rescue by adding Sly1/2 transgenes to mice with NPYq deletions. We demonstrated that SLY1/2 expression in mutant mice decreased proportionally to deletion size, with ~12% of SLY1/2 retained in shSLY sh367 testes.
Title: Rescue of Sly Expression Is Not Sufficient to Rescue Spermiogenic Phenotype of Mice with Deletions of Y Chromosome Long Arm.
this study describes SLy1 as an immunoregulatory protein, which is involved in the generation of adaptive immune responses during L. monocytogenes infection, and provides a model of how SLy1 regulates T-cell proliferation.
Title: SLy1 regulates T-cell proliferation during Listeria monocytogenes infection in a Foxo1-dependent manner.

expression of the Notch signaling mediator RBP-J and the Notch target genes Hes-1 and Hes-5 was markedly reduced in MZ but not FO B cells of Sly1(d/d) mice.
Title: Reduced notch activity is associated with an impaired marginal zone B cell development and function in Sly1 mutant mice.

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.
