Tmeff2 gene and Tmeff2-KO mice. (a) Structure of TMEFF2. TMEFF2 has a signal peptide (SP), two follistatin-like domains (FS I, FS II), an EGF-like domain (EGF), a shedding domain (S) and a transmembrane domain (TM). (b) A schematic of Tmeff2-KO mice. A human PLAP cassette was inserted after the start codon in the first exon. (c) The Tmeff2-KO mutant mice are smaller than their wild type littermates. (d) Genotyping results of Tmeff2-KO mice. (e) Tmeff2 mRNA transcription could not be detected by ISH in mutant mice.
