tRNA-splicing endonuclease subunit sen2; tRNA-intron endonuclease sen2; Hssen2 (TSEN2 SEN2)
Function:
1) one of 2 catalytic subunits of tRNA-splicing endonuclease
2) isoform 2 is a component of a complex with SEN54, but low level of SEN15 & SEN34
3) phosphorylated upon DNA damage, probably by ATM or ATR
Structure: belongs to the tRNA-intron endonuclease family
Compartment: nuclear; may be transiently localized in nucleolus
Alternative splicing: named isoforms=3
Expression:
- isoform 1 & isoform 2 are widely expressed at very low level
Pathology:
- defects in TSEN2 are the cause of pontocerebellar hypoplasia type 2B
