FYN [ENSP00000357656]
FYN oncogene related to SRC, FGR, YES; Implicated in the control of cell growth. Plays a role in the regulation of intracellular calcium levels, with isoform 2 showing the greater ability to mobilize cytoplasmic calcium in comparison to isoform 1. Required in brain development and mature brain function with important roles in the regulation of axon growth, axon guidance, and neurite extension. Blocks axon outgrowth and attraction induced by NTN1 by phosphorylating its receptor DDC
CSF1R [ENSP00000286301]
colony stimulating factor 1 receptor; Protein tyrosine-kinase transmembrane receptor for CSF1 and IL34
