Disease

[SPSY_HUMAN] Defects in SMS are the cause of X-linked syndromic mental retardation Snyder-Robinson type (MRXSSR) [MIM:309583]. Characterized by moderate intellectual deficit, hypotonia, an unsteady gait, osteoporosis, kyphoscoliosis and facial asymmetry. Transmission is X-linked recessive.[1]

Function

[SPSY_HUMAN] Catalyzes the production of spermine from spermidine and decarboxylated S-adenosylmethionine (dcSAM).

About this Structure
