AT4G16340 | locus:2130484 | SPK1 | SPIKE1

Length:	13445
Chromosome Location:	Chr4: 9228185-9241629
Organism . Short Name:	A. thaliana
TAIR Computational Description:	guanyl-nucleotide exchange factors;(source:Araport11)
TAIR Curator Summary:	Encodes SPIKE1 (SPK1), the lone DOCK family guanine nucleotide exchange factor (GEF) in Arabidopsis. SPK1 is a peripheral membrane protein that accumulates at, and promotes the formation of, a specialized domain of the endoplasmic reticulum (ER) termed the ER exit site (ERES). SPK1 promotes polarized growth and cell-cell adhesion in the leaf epidermis. Mutant has seedling lethal; cotyledon, leaf-shape, trichome defects.
TAIR Short Description:	guanyl-nucleotide exchange factors;GTPase binding;GTP binding
TAIR Aliases:	SPK1
