according to the manual (man cut):
-f list
The list specifies fields, separated in the input by the field
delimiter character (see the -d option). Output fields are
separated by a single occurrence of the field delimiter character.
Meaning that it keeps everything before the first space delimiter and removes the rest.

A low-tech way of doing this is to open the file in any text editor and simply delete the part you don't need. This is not advised if you have a large number of sequences.
