Neural Polypyrimidine Tract-Binding Protein
The protein encoded by this gene binds to intronic polypyrimidine clusters in pre-mRNA molecules and is implicated in controlling the assembly of other splicing-regulatory proteins. This protein is very similar to the polypyrimidine tract binding protein (PTB) but most of its isoforms are expressed primarily in the brain. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
Forensic Context
A study in mice demonstrated that the PTBP2 was up-regulated in the ventral tegmental area during the post-addiction phase of nicotine self-administration compared to the pre-addiction phase, a finding validated by in situ hybridization [Fan et al. DOI:10.1016/J.Jgg.2024.08.009].
