Zzef1 - zinc finger, ZZ-type with EF hand domain 1

Enables ubiquitin-like protein ligase activity. Acts upstream of or within several processes, including glutamatergic synaptic transmission; regulation of peptidyl-tyrosine phosphorylation; and visual learning. Located in cell surface; postsynapse; and presynaptic active zone. Is expressed in several structures, including adipose tissue; alimentary system; immune system; nervous system; and reproductive system. Orthologous to human ZZEF1 (zinc finger ZZ-type and EF-hand domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
