Q5GLZ8

Main function of 5'-partner protein: FUNCTION: Probable E3 ubiquitin-protein ligase involved in either protein trafficking or in the distribution of cellular structures. Required for spermatozoon maturation and fertility, and for the removal of the cytoplasmic droplet of the spermatozoon. E3 ubiquitin-protein ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer it to targeted substrates. {ECO:0000250|UniProtKB:Q6PAV2}.

Q9UI47

Main function of 5'-partner protein: FUNCTION: May be involved in formation of stretch-resistant cell-cell adhesion complexes. {ECO:0000303|PubMed:11590244}.
