Mouse (10090)

Genome localization

11 B4[69215 ], X F3-F4|X 65.2 cM[20229 ],


Acts on propane-1,3-diamine, pentane-1,5-diamine, putrescine, spermidine (forming N1- and N8-acetylspermidine), spermine, N1-acetylspermidine and N8-acetylspermidine.

Rate-limiting Description

"Overexpression of the rate-limiting enzyme in polyamine catabolism spermidine/spermine N1-acetyltransferase (SSAT) in transgenic (Tg) mouse leads to accumulation of putrescine in the skin and permanent hair loss at the age of 3 wk." (15737201)
