CTNNBIP1 antisense RNA 1 (CTNNBIP1-AS1)

CTNNBIP1 antisense RNA 1 (CTNNBIP1-AS1) is annotated as a non-coding RNA (long non-coding RNA, lncRNA) transcribed from the opposite strand of the *CTNNBIP1* gene locus. Unlike the protein product of the *CTNNBIP1* gene, which is a negative regulator of the Wnt/β-catenin signaling pathway[3][5], and the related fusion chimeric RNA *CTNNBIP1-CLSTN1* which has been studied in the context of cell proliferation and apoptosis[1][4], there is no substantial evidence in the current literature linking CTNNBIP1-AS1 directly to a recognized molecular function, disease association, or therapeutic targeting. Context and clarification: Most biological and disease relevance is associated with: - The **protein-coding CTNNBIP1 gene** (“Catenin beta-interacting protein 1”), a negative regulator of Wnt/β-catenin signaling[2][3][5]. - The **CTNNBIP1-CLSTN1 chimeric RNA**, shown to regulate cell proliferation and apoptosis, regarded as a “housekeeping chimeric RNA” but is not an antisense RNA[1][4]. CTNNBIP1-AS1 itself does not have substantial published experimental or clinical annotation as a therapeutic target, disease marker, or functional entity (as of mid-2024). Summary: CTNNBIP1-AS1 is not a therapeutic target; information about related *CTNNBIP1* and its fusions should not be conflated with this antisense non-coding RNA. Further clarification or a more detailed target name may be needed to provide structured data of the type typically desired for drug targets.
