Related proteins are phosphorylated at tyrosine in response to mitogenic stimuli and at meiosis.
Forty-two-kilodalton proteins that contain phosphotyrosine in metaphase-arrested Xenopus laevis eggs are closely related to p42, a protein that is phosphorylated at tyrosine when somatic cells are exposed to mitogenic stimuli.
