What's a GeneRIF?

Orthopedia protein (OTP) is specific for lung carcinoids because well-differentiated nonlung neuroendocrine tumors are negative for OTP. OTP preferentially stains typical carcinoids over atypical carcinoids
Title: Orthopedia homeobox is preferentially expressed in typical carcinoids of the lung.
Half of the pulmonary TC tumors expressed OTP.
Title: Immunohistochemical analysis of OTP and NKX6.1 in neuroendocrine tumors of the lung and pancreas.
We tested the functional consequences of the novel human OTP mutations and Q83K as well as the mouse R108W mutant; all affect residues that are highly conserved across species. On a single site response element, wild-type OTP was found to act as a repressor; both R108W and Q153R abolished this repression
Title: Disruption of the homeodomain transcription factor orthopedia homeobox (Otp) is associated with obesity and anxiety.
Our results suggest that OTP may serve as a useful diagnostic marker for lung carcinoid tumors.
Title: Diagnostic Utility of Orthopedia Homeobox (OTP) in Pulmonary Carcinoid Tumors.
Data indicate that low mRNA expression levels of CD44 and orthopedia homeobox (OTP) and high levels of RET, were strongly associated with a low 20-year survival of carcinoid patients.
Title: CD44 and OTP are strong prognostic markers for pulmonary carcinoids.
we successfully identified a novel gene OTP frequently methylated in breast cancer by genome-wide screening. Our results suggest that the OTP gene may play a crucial role in breast carcinogenesis.
Title: Genome-wide identification of OTP gene as a novel methylation marker of breast cancer.

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.
