Title: The recurrent de novo c.2011C>T missense variant in MTSS2 causes syndromic intellectual disability.
The ABBA motif in cyclin A is required for its proper degradation in prometaphase through competing with BUBR1 for the same site on CDC20
Title: The ABBA motif binds APC/C activators and is shared by APC/C substrates and regulators.
these data indicates that the interaction between full-length Abba and Rac1 is implicated in membrane deformation and subjected to a growth factor-mediated regulation through the C-terminal sequence.
Title: Abba promotes PDGF-mediated membrane ruffling through activation of the small GTPase Rac1.

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.
