SMP1 Pre-mRNA splicing Prp18-interacting factor [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: SMP1
Official Full Name: Pre-mRNA splicing Prp18-interacting factor
Primary source: TAIR:AT1G65660
Locus tag: AT1G65660
See related: Araport:AT1G65660
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F1E22.4; F1E22_4; SWELLMAP 1
Summary: Encodes a CCHC zinc finger protein that may function as a step II splicing factor. In an epigenetic allele of SMP1 (in which SMP1 and SMP2 mRNA is reduced) organs are smaller and contain fewer cells.
