Genes affected
PLXNA1 (HGNC:9099): (plexin A1) Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including generation of neurons; regulation of GTPase activity; and regulation of cell shape. Predicted to act upstream of or within dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection morphogenesis; and regulation of smooth muscle cell migration. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
