Summary: Enables histone H2A ubiquitin ligase activity. Involved in several processes, including heterochromatin formation; meiotic nuclear division; and ubiquitin-dependent protein catabolic process via the N-end rule pathway. Acts upstream of or within male meiosis I and ubiquitin-dependent protein catabolic process. Located in chromatin. Part of ubiquitin ligase complex. Is expressed in several structures, including alimentary system; endocrine gland; eye; genitourinary system; and trachea. Orthologous to human UBR2 (ubiquitin protein ligase E3 component n-recognin 2). [provided by Alliance of Genome Resources, Dec 2024]

These data suggest that Tex19.1 and Ubr2 are required for mouse spermatocytes to accumulate sufficient Spo11-dependent recombination to ensure that the homology search is consistently successful, and reveal a hitherto unknown genetic pathway promoting meiotic recombination in mammals.

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.
