PHS1 poor homologous synapsis 1 [ Arabidopsis thaliana (thale cress) ]

Gene ID: 837614, updated on 6-May-2021

Summary

Gene symbol
PHS1
Gene description
poor homologous synapsis 1
Primary source
Araport:AT1G10710
Locus tag
AT1G10710
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
POOR HOMOLOGOUS SYNAPSIS 1; T16B5.15
Summary
Computational predictions suggested the presence of a small cysteine-rich protein beginning in intron 9 (Silverstein 2007), but subsequent analysis revealed that this region contains a tenth exon for the At1g10710 gene. PHS1 regulates recombination and pairing of homologous chromosomes during meiotic prophase by controlling transport of RAD50 from cytoplasm to the nucleus.
