General annotation (Comments)

Function

Part of a ternary complex that binds to the downstream control sequence (DCS) of the pre-mRNA. Mediates exon inclusion in transcripts that are subject to tissue-specific alternative splicing. May interact with single-stranded DNA from the far-upstream element (FUSE). May activate gene expression. Also involved in degradation of inherently unstable mRNAs that contain AU-rich elements (AREs) in their 3'-UTR, possibly by recruiting degradation machinery to ARE-containing mRNAs By similarity. Binds to the dendritic targeting element and may play a role in mRNA trafficking. Ref.1

Subunit structure

Part of a ternary complex containing FUBP2, PTBP1, PTBP2 and HNRPH1. Interacts with PARN By similarity.

Subcellular location

Nucleus. Cytoplasm. Note: A small proportion is also found in the cytoplasm of neuronal cell bodies and dendrites. Ref.1

Sequence similarities

Belongs to the KHSRP family.

Contains 4 KH domains.
