Expression profiling of NPTNbeta showed significantly high expression levels in lung cancer cell lines. NPTNbeta has strong ability to induce cancer-related cellular events, including anchorage-independent growth, motility and invasiveness, in lung cancer cells in response to extracellular S100A8/A9, eventually leading to the expression of a cancer disseminative phenotype in lung tissue in vivo.

these results indicate that epilation induces McSCs activation through EDN3/EDNRB signaling and in turn leads to skin and hair hyperpigmentation. The findings suggest that EDN/EDNRB signaling may serve as a potential therapeutic target to promote repigmentation in hypopigmentation disorders.

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_001161363.2 → NP_001154835.1 neuroplastin isoform c precursor

See identical proteins and their annotated locations for NP_001154835.1

Status: REVIEWED

Description

Transcript Variant: This variant (c) uses an alternate in-frame splice site in the 3' coding region compared to variant b. This results in a shorter protein (isoform c), compared to isoform b.
