Annotated Information

Name

PINCR:p53-induced noncoding RNA

Characteristics

PINCR is a ~1.8 kb noncoding RNA that is transcribed from cheomosome X (Xp11.3) [1].

Cellular Localization

PINCR is highly enriched in the nucleus [1].

Function

PINCR is induced ~100-fold after DNA damage and exerts a prosurvival function in human colorectal cancer cells (CRC) in vitro and tumor growth in vivo [1]. PINCR regulates a subset of p53 targets involved in G1 arrest and apoptosis (BTG2, RRM2B and GPX1) in human colorectal cancer cells by binding to Matrin 3, and plays an important role in p53-dependent G1 arrest [1].

Regulation

PINCR promoter contains p53RE, and PINCR is a direct target of p53 [1].

Diseases

colorectal cancer [1]

Expression

PINCR is induced ~100-fold after DNA damage [1].

Conservation

Mature PINCR transcript and the transcription start site are quite conserved among primates but poorly conserved between human and mouse [1].
