What's a GeneRIF?

While PIWIL1 and YBX2 were associated with translationally inactive messenger ribonucleoproteins and translating polyribosomes, PAPOLB was present almost exclusively in the mRNA-free fractions of sucrose gradients. These results suggest that PAPOLB may regulate spermiogenesis through a pathway distinct from that mediated by chromatoid body-associated factors.
Title: PAPOLB/TPAP regulates spermiogenesis independently of chromatoid body-associated factors.
expression of GSG1 stimulates TPAP targeting to the ER, suggesting that interactions between the two proteins lead to the redistribution of TPAP from the cytosol to the ER
Title: Germ cell-specific gene 1 targets testis-specific poly(A) polymerase to the endoplasmic reticulum through protein-protein interactions.
propose that TPAP governs germ cell morphogenesis by modulating specific transcription factors at posttranscriptional and posttranslational levels
Title: Regulation of spermatogenesis by testis-specific, cytoplasmic poly(A) polymerase TPAP.
spermatogenesis requires the cytoplasmic elongation of the mRNA poly(A) tails catalyzed by TPAP
Title: Transgenic expression of testis-specific poly(A) polymerase TPAP in wild-type and TPAP-deficient 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.
