CDKN2B-AS1 can inhibit the transcription of ADAM10 via DNMT1-mediated ADAM10 DNA methylation, consequently preventing inflammatory response of atherosclerosis and promoting cholesterol efflux.
Title: Long non-coding RNA CDKN2B-AS1 reduces inflammatory response and promotes cholesterol efflux in atherosclerosis by inhibiting ADAM10 expression.
Our results demonstrate that a SNP downstream of TMCO1, rs4657473, is associated with POAG in an AA population. Our studies suggest a regulatory role for the previously POAG-associated locus near the TMCO1 gene that may affect gene expression.
Title: SNP located in an AluJb repeat downstream of TMCO1, rs4657473, is protective for POAG in African Americans.
Thus we provide evidence that cerebrofaciothoracic dysplasia (CFTD) may be more common than previously thought. The patients presented here further delineate the phenotypic spectrum of CFTD and provide evidence for a recurrent pathogenic variant in TMCO1.

An essential role of TMCO1 in osteogenesis mediated by local Ca(2+)/CaMKII signaling in osteoblasts.TMCO1 levels were significantly decreased in bone from both osteoporosis patients.
Title: TMCO1-mediated Ca(2+) leak underlies osteoblast functions via CaMKII signaling.
TMCO1 recruited the PH domain and leucine-rich repeat protein phosphatase 2 (PHLPP2) to dephosphorylate pAKT1(serine 473) (S473). Mutagenesis at S60 of the TMCO1 protein released TMCO1-induced cell-cycle arrest and restored the AKT pathway in BFTC905 cells. Stable TMCO1 (wild-type) overexpression suppressed, whereas T33A and S60A mutants recovered, tumor size in xenograft 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.

NM_001256164.1 → NP_001243093.1 calcium load-activated calcium channel isoform b

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses two alternate in-frame splice sites in the 5' coding region, compared to variant 1. This results in a shorter protein (isoform b), compared to isoform a.

NR_045818.1 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) uses an alternate splice site in the 5' terminal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
