How can I add a function inside my .bash_profile?

I need to use a modified grep function to find certain jobs on our cronjob repositories (cvs & git) in a more automated way. So I got these functions already made for that job, but not sure how to enter them into my profile so I can use them like any other Unix command.

The usage should be something like: grepcon <text_to_search>

The function is as follows:

function grepcron {

   echo 'in cvs'
   cd /somedir/otherdir
   grep -irn $1 country1/crontab.* country2/crontab.*
   cd -

   echo 'in git'
   cd /somedir/crontabs/user1/
   grep -irn $1  
}

Is there any way I can add this to my profile? So every time I log into my user, it loads automatically.
