ALDOA encodes fructose-bisphosphate aldolase A, the muscle/red-cell isozyme of the ubiquitous class-I fructose-bisphosphate aldolase (three vertebrate isozymes exist: A in muscle, B in liver, C in brain). It is a cytosolic homotetramer that uses a Schiff-base (active-site lysine) mechanism to catalyze the reversible aldol cleavage of beta-D-fructose 1,6-bisphosphate into dihydroxyacetone phosphate (DHAP) and D-glyceraldehyde 3-phosphate (EC 4.1.2.13), the fourth step of glycolysis, and the reverse aldol condensation in gluconeogenesis. Aldolase A is highly abundant in skeletal muscle and erythrocytes. Beyond catalysis it is a well-documented moonlighting protein that binds F-actin and other cytoskeletal components (and the actin nucleation-promoting factor WASP) via its active-site region, links glycolysis to cytoskeletal dynamics, and binds RNA. Loss-of-function variants cause glycogen storage disease type XII (aldolase A deficiency), presenting as hereditary nonspherocytic hemolytic anemia frequently accompanied by myopathy, exercise intolerance and rhabdomyolysis (often triggered by febrile illness).

Summary: Phylogenetic (PAN-GO) inference of the core catalytic molecular function of aldolase A, transferred across the class-I fructose-bisphosphate aldolase family (PANTHER PTHR11627). This is correct and central: aldolase A cleaves fructose-1,6-bisphosphate to DHAP and glyceraldehyde-3-phosphate (EC 4.1.2.13).
Reason: Correct core molecular function, well supported by direct enzymatic and structural studies of the human muscle enzyme and consistent across the family.

Summary: This annotation cites PMID:17329259, which reports the structural basis of aldolase binding to the Wiskott-Aldrich syndrome protein (WASP) via a hydrophobic active-site pocket, competitive with substrate and with actin/cortactin. The paper concerns actin-related (WASP) binding, not tubulin; tubulin binding is not supported by this reference.
Reason: The cited reference does not establish tubulin binding; it demonstrates WASP/actin- pathway binding at the aldolase active site. Marked as over-annotated rather than removed (aldolase is broadly promiscuous, and this is a TAS from the curator).

description: >-
ALDOA encodes fructose-bisphosphate aldolase A, the muscle/red-cell isozyme of the
ubiquitous class-I fructose-bisphosphate aldolase (three vertebrate isozymes exist:
A in muscle, B in liver, C in brain). It is a cytosolic homotetramer that uses a
Schiff-base (active-site lysine) mechanism to catalyze the reversible aldol cleavage
of beta-D-fructose 1,6-bisphosphate into dihydroxyacetone phosphate (DHAP) and
D-glyceraldehyde 3-phosphate (EC 4.1.2.13), the fourth step of glycolysis, and the
reverse aldol condensation in gluconeogenesis. Aldolase A is highly abundant in
skeletal muscle and erythrocytes. Beyond catalysis it is a well-documented moonlighting
protein that binds F-actin and other cytoskeletal components (and the actin
nucleation-promoting factor WASP) via its active-site region, links glycolysis to
cytoskeletal dynamics, and binds RNA. Loss-of-function variants cause glycogen storage
disease type XII (aldolase A deficiency), presenting as hereditary nonspherocytic
hemolytic anemia frequently accompanied by myopathy, exercise intolerance and
rhabdomyolysis (often triggered by febrile illness).

The cited reference does not establish tubulin binding; it demonstrates WASP/actin-
pathway binding at the aldolase active site. Marked as over-annotated rather than
removed (aldolase is broadly promiscuous, and this is a TAS from the curator).
