Taxonomic identifier

559292 [NCBI]

Taxonomic lineage

Eukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length	355 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in splicing pre-mRNA of the A1 cistron and other genes that are important for cell growth.
Subunit structure	Heterodimer Probable.
Subcellular location	Cytoplasm. Nucleus. Note: This protein lacks a nuclear localization signal, it may interact in the cytoplasm with a component of spliceosomes via the leucine-zipper and then be transported into the nucleus.
Miscellaneous	Present with 7330 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the AAR2 family.
