Verifying Sizes of Human Pituitary Proteins

[sotellme]

Can anyone please help me to find the sizes (Da) for these human pituitary proteins? i have looked for them in Entrez and other bioinformatic sites, but am really not sure if they are right. Please, recheck them for me. Thanks a bunch!


1. Glycoprotein hormones alpha chain

i have a vERY hard time with this one. from the Entrez result i only get
Glycoprotein hormones alpha chain precursor form (13041 Da). i need an active form. What is the size?



2. Variant hepatic nuclear factor 1
From entrez i got an active form of 166aa. Is this correct?

3. Human B-actin
active form: 41737 Da. Correct?


4. Folate receptor alpha
active form: 96 aa. Correct?


Thanks !

I'll give you the same advice I just gave to mountain in this thread:

You have to read the literature for this sort of stuff.

For example, for #1, searching for "glycoprotein hormone alpha human" (without quote marks), I got a result of 6079 articles in PubMed. You'll have to work through them to find what you need.

Here's the address for PubMed:

You can always predict the molecular weight and post-translational modification of your protein if you have the amino acid sequence:
