Harmonizome 3.0

pleckstrin and Sec7 domain containing

This gene encodes a Plekstrin homology and SEC7 domains-containing protein that functions as a guanine nucleotide exchange factor. The encoded protein regulates signal transduction by activating ADP-ribosylation factor 6. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

IQ motif and Sec7 domain 1

Predicted to enable protein kinase binding activity. Predicted to be involved in several processes, including positive regulation of focal adhesion disassembly; positive regulation of keratinocyte migration; and regulation of postsynaptic neurotransmitter receptor internalization. Located in nucleolus. Implicated in intellectual developmental disorder with short stature and behavioral abnormalities and lung adenocarcinoma. Biomarker of lung non-small cell carcinoma.

IQ motif and Sec7 domain 3

Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including activation of GTPase activity; postsynapse organization; and regulation of small GTPase mediated signal transduction. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Mar 2025]

IQ motif and Sec7 domain 2

This gene encodes a guanine nucleotide exchange factor for the ARF family of small GTP-binding proteins. The encoded protein is a component of the postsynaptic density at excitatory synapses, and may play a critical role in cytoskeletal and synaptic organization through the activation of selected ARF substrates including ARF1 and ARF6. Mutations in this gene have been implicated in nonsyndromic X-linked cognitive disability. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

pleckstrin and Sec7 domain containing 2

Predicted to enable guanyl-nucleotide exchange factor activity and phospholipid binding activity. Predicted to be involved in regulation of ARF protein signal transduction. Predicted to be located in cleavage furrow and ruffle membrane. Predicted to be active in glutamatergic synapse and postsynapse. [provided by Alliance of Genome Resources, Mar 2025]

pleckstrin and Sec7 domain containing 4

Predicted to enable guanyl-nucleotide exchange factor activity and phospholipid binding activity. Predicted to be involved in regulation of ARF protein signal transduction. Located in ruffle membrane. [provided by Alliance of Genome Resources, Mar 2025]
