CC -!- FUNCTION: Broad specificity cytosolic 5'-nucleotidase that catalyzes
CC the dephosphorylation of 6-hydroxypurine nucleoside 5'-monophosphates
CC (PubMed:1659319, PubMed:9371705, PubMed:10092873, PubMed:12907246). In
CC addition, possesses a phosphotransferase activity by which it can
CC transfer a phosphate from a donor nucleoside monophosphate to an
CC acceptor nucleoside, preferably inosine, deoxyinosine and guanosine
CC (PubMed:1659319, PubMed:9371705). Has the highest activities for IMP
CC and GMP followed by dIMP, dGMP and XMP (PubMed:1659319, PubMed:9371705,
CC PubMed:10092873, PubMed:12907246). Could also catalyze the transfer of
CC phosphates from pyrimidine monophosphates but with lower efficiency
CC (PubMed:1659319, PubMed:9371705). Through these activities regulates
CC the purine nucleoside/nucleotide pools within the cell (PubMed:1659319,
CC PubMed:9371705, PubMed:10092873, PubMed:12907246).

CC -!- DISEASE: Spastic paraplegia 45, autosomal recessive (SPG45)
CC [MIM:613162]: A form of spastic paraplegia, a neurodegenerative
CC disorder characterized by a slow, gradual, progressive weakness and
CC spasticity of the lower limbs. Rate of progression and the severity of
CC symptoms are quite variable. Initial symptoms may include difficulty
CC with balance, weakness and stiffness in the legs, muscle spasms, and
CC dragging the toes when walking. In some forms of the disorder, bladder
CC symptoms (such as incontinence) may appear, or the weakness and
CC stiffness may spread to other parts of the body. Some SPG45 patients
CC manifest intellectual disability, contractures and learning disability.
CC {ECO:0000269|PubMed:24482476, ECO:0000269|PubMed:28884889}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the 5'(3')-deoxyribonucleotidase family.
