Chain A,B,C,D (HCD2_RAT | O70351)

molecular function
	GO:0047015	3-hydroxy-2-methylbutyryl-CoA dehydrogenase activity	Catalysis of the reaction: NAD+ + 2-methyl-3-hydroxybutyryl-CoA = NADH + H+ + 2-methylaceto-acetyl-CoA.
	GO:0003857	3-hydroxyacyl-CoA dehydrogenase activity	Catalysis of the reaction: (S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH + H(+).
	GO:0051287	NAD binding	Interacting selectively and non-covalently with nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NAD+, or the reduced form, NADH.
	GO:0018454	acetoacetyl-CoA reductase activity	Catalysis of the reaction: (R)-3-hydroxyacyl-CoA + NADP+ = 3-oxoacyl-CoA + NADPH + H+.
	GO:0001540	amyloid-beta binding	Interacting selectively and non-covalently with amyloid-beta peptide/protein and/or its precursor.
	GO:0004303	estradiol 17-beta-dehydrogenase activity	Catalysis of the reaction: estradiol-17-beta + NADP+ = estrone + NADPH + H+.
	GO:0030331	estrogen receptor binding	Interacting selectively and non-covalently with an estrogen receptor.
	GO:0042802	identical protein binding	Interacting selectively and non-covalently with an identical protein or proteins.
	GO:0016491	oxidoreductase activity	Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
	GO:0005496	steroid binding	Interacting selectively and non-covalently with a steroid, any of a large group of substances that have in common a ring system based on 1,2-cyclopentanoperhydrophenanthrene.
	GO:0030283	testosterone dehydrogenase [NAD(P)] activity	Catalysis of the reaction: testosterone + NAD(P)+ = androst-4-ene-3,17-dione + NAD(P)H + H+.
biological process
	GO:0033327	Leydig cell differentiation	The process in which a relatively unspecialized cell acquires specialized structural and/or functional features of a Leydig cell. A Leydig cell is a testosterone-secreting cell in the interstitial area, between the seminiferous tubules, in the testis.
	GO:0007569	cell aging	An aging process that has as participant a cell after a cell has stopped dividing. Cell aging may occur when a cell has temporarily stopped dividing through cell cycle arrest (GO:0007050) or when a cell has permanently stopped dividing, in which case it is undergoing cellular senescence (GO:0090398). May precede cell death (GO:0008219) and succeed cell maturation (GO:0048469).
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
	GO:0051289	protein homotetramerization	The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.
	GO:0008033	tRNA processing	The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group.
cellular component
	GO:0005739	mitochondrion	A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
